Six quiet days, and one you’d rather not log.

Days 1–6 2,000 each, logged normally

Day 7, eaten 3,000

Written down as 2,250

What day 7 actually was 3,000

What you estimate instead 2,250

25% under. A bad estimate.

True daily average 2,143

If you skip day 7 2,000 143 too low

If you estimate it 2,036 107 too low
