I curiously have found no references to Level as of yet in terms of Accuracy, but I have come across a strange phenomenon that every attack, no matter what it is (unless your Class/Row byte reads 7F somehow...) will gain a +1/4 bonus to their accuracy, despite what is listed there.
I cannot say for certain that Focus and Jump appear to get an Accuracy bonus from any thing I've looked at thus far. Viewing the Accuracy altering field their accuracy seems to do the +1/4 like every other attack does. It may be something outside or the normal routine perhaps.
