Two calculators. Both of them work only from what a listing prints, both print the rule they follow, and both switch off any input that cannot change the answer, with the reason written on it.
Adds up slots
Stack Check
Choose a condition, then choose a listing for each rung the condition asks for. The placket shows what is closed and what is still open, including the one rung nothing here can close.
It does not add up degrees. Not one listing in this catalog states a temperature range, so there is nothing to add up.
Counts printed ranges
Size Range Check
Choose a category and a size, and see how many listings print a range that includes it, how many print a range that leaves it out, and how many print no range at all.
It gives no advice about which size to pick, and it never compares one seller’s range against another’s.
