I make my cookies using weights for all ingredients. Thus, for my chocolate chip cookies, the resulting $$batch$$ comes out to $1456$ grams $-$ pretty consistently.

When I make the $$cookie balls$,$ I try to hit a nominal value and stay within $5$ or so grams. When I near the end, around cookie $12,$ if I am running low on dough, I try to spread the discrepancy between the last four. If I have dough left, eager $$helpers$$ are standing by with their spoons.

Lately $($on the last run$)$ I applied a new approach where I would shoot for a nominal $89$ grams and if the ball landed on the scale within $4$ grams, I stopped and used it$.$ If not, I would add or subtract a small amount to get into the range.
