Measuring typing speed at home: a fixed-text, fixed-duration protocol with the word and error rules written down
A proposed protocol for a personal typing-speed record in which the definitions are part of the log: a standard word is defined as five characters including spaces, gross and net rates are computed by stated formulas, the keyboard, layout, software and correction setting are logged per session, three timed trials of fixed length are run on texts of a fixed kind, and the median is reported; no rate, target or improvement is claimed.

Which household records fix the start and end of a power outage after the fact, and how far have they disagreed?
Open question: after a power cut a household has several clocks of the event, such as the utility's notice, a UPS log, a router's uptime, a home server's reboot records (the last(1) manual page states that last reboot produces a record of reboot times, and journalctl can list boots with the timestamps of each boot's first and last message), a battery clock that kept time and a mains clock that flashes; which of these have households actually used, how far did they disagree, and which gave the earliest and latest bounds?

A grocery price log with the unit price computed from the pack: barcode identity, pack quantity, shelf price and promotion flag per observation
A proposed record-only protocol for logging grocery prices in which each observation carries the product's barcode number as its identity, the pack quantity as printed, the shelf price and any promotion or loyalty condition, and a unit price computed by the household in a stated unit, following the definition in EU Directive 98/6/EC of the unit price as the final price per kilogramme, litre, metre, square metre or cubic metre; a changed pack size becomes a new product row, and no purchasing advice or inflation figure is given.

Household log entries written from memory at the end of the day show more rounded values than entries written at the moment of reading
Hypothesis: when a meter, scale or thermometer reading is written down hours later from memory, the recorded value is more often a round number (ending in 0 or 5, or with fewer decimals) than when it is written at the instrument; a proposed within-household test with alternating days and photographs as the reference, with no claim about which value is closer to the truth.

An expense categorisation log as a method: frozen category list, numbered edge-case rules and a re-coding check
A proposed documentation method for household spending records: freeze a category list with definitions before coding, keep one row per transaction with amount, currency, payee as printed and a rule identifier, turn every edge-case decision into a numbered rule, and re-code a blind sample monthly to measure self-agreement; it produces interpretable category totals and gives no financial advice.

测量通勤时间：从门到门的计时规程
一项为重复行程计时的拟议规程：固定起点和终点，在两处记录带 UTC 偏移的 RFC 3339 时间戳，可选记录分段边界，并设置条件栏（星期、路线变体、天气、异常情况），让变化可以归因而非依赖记忆；本文不推荐任何路线。

Logging a consumer PM2.5 sensor: what to record beside each reading and what the number cannot say
A consumer particulate sensor reports an estimate of the mass of particles 2.5 micrometres and smaller; the EPA states that such sensors come with lower accuracy and higher uncertainty than regulatory monitors, describes collocation with reference instruments as an effective way to assess them, and notes that an outdoor correction may not apply indoors and that changing temperature and humidity may affect some sensors. A household log therefore stores the raw value, the averaging interval, placement, indoor events and the nearest official monitor's value with its distance.

A parcel delivery time log: order, dispatch, tracking and door timestamps on one row, with the carrier's scan and the observed arrival kept apart
A proposed record-only protocol for logging each parcel's timeline as timestamps in the RFC 3339 Internet Date/Time Format with UTC offsets, taken from the order confirmation, the dispatch notice, the carrier's tracking events and the household's own note of the arrival, with the carrier, service, delivery place and each attempt recorded; the carrier's delivered scan and the observed arrival are separate columns, and no carrier comparison or delivery-time claim is made.

A wrist step counter and a pocket phone diverge more on days with many short walking bouts and occupied hands
Hypothesis: two consumer step counters worn by one person, one on the wrist and one in a trouser pocket, disagree by a larger fraction on days the diary marks as many short walks or hands occupied (pram, bags, trolley) than on days with a few long walks, because the two devices read different body motions; a daily log with both devices stated is proposed as the test and no measurement is reported.

Which household observation protocols have been carried out by a second household, and what had to change to make the repeat comparable?
Open question: the wiki publishes observation protocols for meters, plants, rooms and kitchens, but a protocol is only shown to be reproducible when someone else follows it; which protocols have been repeated by another household, which steps were ambiguous, and what did the second household have to substitute?

A reading log with pages, minutes and a recall note per session
A proposed protocol for a personal reading log: one header per book with format and page basis, one row per session with start and end time, start and end page, place and interruptions, and a one-line recall note written before the book is reopened, so that pace and retention can be looked at per book without claiming a reading-speed measurement.
-
A car or bicycle trip log: distance, duration and conditions with the measuring instrument stated
A proposed protocol for a per-trip record: name the instrument (odometer, wheel sensor with its circumference setting, or a GPS app) in the header and never mix instruments in one distance column, timestamp start and end in RFC 3339 form, log route, stops and conditions, and treat repeated-route spread as expected where gps.gov states that smartphone accuracy worsens near buildings, bridges and trees.

A personal typing error log with categories: aligning typed output against the source and coding each difference by a written rule
A proposed protocol for turning the stored output of typing trials into a categorised error log: align the typed text against the source with a difference tool such as Python's difflib, whose get_opcodes method returns replace, delete, insert and equal spans with index ranges, code every non-equal span with a fixed category list (adjacent-key substitution, transposition, omission, insertion, doubled letter, case, word substitution, autocorrection, other) with tie-break rules written before coding, and count per session with keyboard and software in the header; no error rate or cause is claimed.

Indoor line-drying time tracks the gap between room temperature and dew point more closely than relative humidity alone
Hypothesis: the National Weather Service describes the dew point as the temperature to which air must be cooled to reach 100 % relative humidity and notes that relative humidity can be misleading because the same figure means different moisture at different temperatures; the proposal is that, for similar wet loads weighed at intervals on the same indoor rack, the time to a stable mass is ordered better across days by the difference between room temperature and dew point than by relative humidity, in a within-household comparison; no result is claimed.

A bird or wildlife sighting log with the location precision stated: Darwin Core fields for a personal notebook
A proposed protocol for a personal sighting log that borrows the Darwin Core terms used by biodiversity databases: an ISO 8601 event date and time, decimal coordinates with the datum named, a non-zero coordinateUncertaintyInMeters that reflects how the position was obtained, an individual count, the observer's identification confidence and the evidence, and an explicit note when a location is deliberately generalised.

Organising a personal photo archive: capture date from EXIF, exact duplicates by checksum, and an inventory that is checked yearly
A proposed method for bringing photos from phones, cameras and messaging apps into one archive: take the date from the EXIF DateTimeOriginal tag and its time-zone offset where present and mark files where only the file system date exists, find byte-identical copies with SHA-256 checksums before looking for re-encoded near-duplicates by eye, keep an inventory file that names every folder, and follow the Library of Congress advice to keep at least two copies and check readability yearly.

How comparable are personal reading-speed measurements between paper, e-reader and phone for the same reader and text?
Open question: when one person times themselves on passages of counted words in print, on an e-ink reader and on a phone, which parts of the set-up (typography, line length, passage choice, comprehension check, time of day) have to be held constant before the words-per-minute figures can be compared, and has anyone kept such a log long enough to see whether the ordering of the three formats is stable?
