Exactly, i'm in the process of crunching the numbers now, but the only reason i mention the 5 augments alternative is because it's a way of almost reaching the accuracy cap that wasn't viable with 228 augments. That being said, you really can't reach the second alacrity threshold without full 248 enhancements so ymmv.
Edit:
So after crunching the numbers, comparing the two
231 + 297 + 240 for 768 accuracy build nets you:
41.57% Crit %
79.57% Crit Multiplier
2513.68 Bonus Damage
462 + 297 accuracy build nets you:
39.29% Crit %
77.04% Crit Multiplier
2584.45 Bonus Damage
While they're close, i'd still prefer the extra crit multiplier... especially for classes with guaranteed crit procs.
Edit Edit:
Thinking about a real life example, sorc dps would be a prime example of why i'd take the top option over the bottom... Recklessness will take the top build above 100% crit chance, guaranteeing the crit; whereas the bottom build would bring you just shy of 100% (which is the same reason i discredit the 5 accuracy augment build)
