Black Mage Sanctuary - A Guide to DPS

[randysquirrel]

So tonight I missed in A8S. Was very noticeable as it was the very first cast of the encounter.

I run exactly 591 acc, so am wondering if anyone can think of a reason why this might be?
I actually have 574 acc, so with food (+3%), this give me 591 acc.

Does anyone know if the game considers decimals? ie, with food, this actually gives me 591.22 acc

The only things I can possibly think of, is either the game considers decimals, and the acc cap is actually like 591.3, or am I subject to something like frontal acc here (as stated this was the very first cast of the fight, when the boss is facing the group, AFAIK caster acc is static regardless of which way boss is facing)

This is the only miss I've recorded.
Just wondering if anyone else has any other ideas what it could be... otherwise I guess the cap is higher than 591?
I instantly remembered this post, and checked that my food hadn't fallen off... and it hadn't, so it isn't that
