266acc * 1.11 = 295.26.
This is disregarding the additional 20dex and 22luk that comes with the helmet. If the acc-%-bonus affects equip stats, it's supposed to be (266 + 20*0.6 + 22*0.3) * 1.11 = 316 acc. If the acc-%-bonus does not affect equip stats, it's supposed to be 266*1.11 + (20*0.6 + 22*0.3) = 314 acc.
The fact that it remains at 295 perplexes me. There's also the inexplicable 353 * 1.09 avoid, being 378 instead of 384.
