For count-based filling, a bottle containing more pieces than its specified fill count.
Also called: giveaway; bottle overcount; overfilled bottle.
Does overfill mean the counter counted too many?
Overfill means the bottle actually contains more pieces than its target. It does not, by itself, say whether the counting indication was too high, too low or correct at an earlier point in the process.
In a simplified system that stops at the indicated target, missing a product event can allow an extra piece through before the target is reached. For example, 60 indicated against 61 actual pieces gives a counting error of −1 despite an overfilled bottle. This illustration assumes all pieces reach the same bottle.
They can cancel in a net arithmetic total, but that does not remove the extra pieces given away in overfilled bottles or make short bottles correct. Count positive excess separately when that is the quantity being discussed.
Giveaway is the excess product supplied beyond the target. Calculate it for a defined group of bottles in a stated unit; the percentage of correctly filled bottles measures a different outcome.
Positive extra pieces = sum of max(actual bottle count − target count, 0)
Is a heavy bottle necessarily overfilled by count?
A higher gross weight does not uniquely identify an extra piece when unit weights or packaging tare differ. Count and weight are different quantities; a weight-based decision needs its own stated basis.
Also distinguish an overfilled reference bottle from a successful physical reject. A detection decision does not by itself show where that bottle went.
