1-correction simply refers to the step during damage calculation when negative numbers (due to defense, etc) are "corrected" and become 1. Presumably this is also the same step as "99999-correction" as well, but I dunno.

It's better explained as a limiter. If the number output for one hit is lower than 1 and is a hit (that is, is not a miss), it will deal 1 instead. If the number is higher than 99 999, it will lower down and deal 99 999 instead.
