Twelve rows a string match cannot reach
On this page11
On this shelf the fit table records 9,273 pairs
Counting only pairs where both the container and the closure are on this shelf. Those reach 228 of the 251 containers, with between 1 and 67 fitting closures each.
And 31 of the 288 closures fit nothing here
They are on the shelf because they fit something in the wider catalog. Twenty three containers have no recorded fit at all, in either direction.
The obvious question is whether the table adds anything to the neck finish field
Because a container and a closure recording the same neck notation are already a presumptive match without any table at all.
For 216 containers the two methods agree exactly
216 containers here record a neck finish that at least one closure here also records, and for every one of those 216 the number of recorded fits equals the number of same-notation closures. Zero disagreement in either direction.
Which confirms what the one stated basis says
The table is derived from the notation. It is not an independent body of evidence and it does not contradict the field it came from.
And then twelve containers have a fit while recording no neck finish at all
Those twelve are where the table earns its place, because a string match has nothing to match on and returns nothing.
All twelve are polypropylene round tubs
A tub takes a lid that seats on a rim rather than a cap that threads onto a neck. There is no thread notation to record, so the neck finish field is empty and the relationship has to be carried some other way.
Which is a useful general observation about an empty field
Those twelve rows are not missing data. They are rows where the field does not apply, and a filter on neck finish treats the two situations identically and wrongly.
So the honest summary of the table is narrow and positive
It restates the neck notation for 216 containers and it covers twelve more that the notation cannot describe. That is a real contribution and it is smaller than fifty five thousand rows suggests.
And 23 containers remain unanswered
No recorded fit and no same-notation closure on this shelf. Which is an unanswered question rather than a negative answer, and it is the same distinction the quilting property draws about an affirmative none.
