I
How it went
two notes · one failureAverage loss of 13.48 g per piece per day, or 4.21% of initial weight per day. The rate is not linear: small pieces lose a far higher percentage daily (A10 at 10.23%/day) than large ones (A5 at 2.02%/day), so a single drying window across mixed sizes will always over-dry the small pieces.

NOTE · OBSERVATION A8 was never recorded
Piece A8 (367 g) has no final weight or cutting date in the log.

NOTE · RESULT Drying rate is size-dependent
Daily loss ≈ 4.21% of initial weight, but the spread runs from 2.02% (533 g piece) to 10.23% (110 g piece). Treat the average as a planning figure for medium pieces only and pull the small ones early.
