Sixty one ways to close it
On this page11
Most containers on this shelf have an abundance of closures
The number of closures sharing a container’s nominal neck finish runs from 1 to 66, with a median of 61. The median container can be closed sixty one different ways from this shelf alone.
Which is a consequence of how few finishes the shelf uses
The two widest common finishes carry 56 containers each, and the closure side concentrates on the same sizes. A popular finish produces a large mutual match count on both sides.
So for most of the shelf the closure is a choice and not a constraint
Color, material, liner and price are all available to choose among, which is a comfortable position and is not the situation everywhere.
Thirty six containers have no matching closure on this shelf
Which is a seventh of the shelf. For those rows the pairing exercise returns nothing and a complete unit cannot be priced from this shelf.
Nineteen of the thirty six record no neck finish at all
So the match fails because the field is empty rather than because no closure exists. That is an unanswered question, not a negative answer, and the two should not be read the same way.
Which leaves seventeen rows that are a genuine gap
Seventeen containers carry a recorded neck finish for which no closure on this shelf is listed. That is the honest count of the problem, and it is a much smaller number than the thirty six.
And it is a fact about this shelf rather than about the catalog
A curated shelf cannot show what it excluded. A finish with no closure here may be well served elsewhere in the catalog, and nothing on this page says otherwise.
The minimum match count of one is worth noting on its own
At least one container on this shelf has exactly one closure that fits it here. Which means no choice of liner, color or price, and a single point of failure if that row goes unavailable.
Availability is a separate question and it moves
The shelf-wide snapshot is 159 of 251 containers and 213 of 288 closures marked available. A match count of one against an unavailable closure is a different situation from a match count of one.
So the useful reading is the pair of numbers together
How many closures fit, and whether any of them can be had. Either figure alone will mislead, and neither is a property of the container.
