It may be because it is cheaper and easier to add more sugar and pectin
that to have to mess around with cooking it until it passes the set test
on its own.

That is a good question. When we used the Imperial system most things
came in some fraction of an Imperial quart gallon or pound. When we
switched to SIM we used the same sizes ... but in metric, like the
popular 12 oz size for pop and beer became 355 ml. The best I suggest
is that they bought a stock size jar and their product fills the
containers to an acceptable level for canning with that odd number.
