I do lots of mandies, I know you didn't get a 23% monster accuracy rate on them. Something is wrong with your parser or it's counting blinked attacks as "miss's".
If you were doing the DC loop of crows -> mandies then did you run across the zone to the crabs or do the ones on the beach nearby?
Mandies are MNKs and have A+ skill for accuracy. Crabs are PLDs and have the same A+ skill. Birds are thieves and have A- skill. Evasion is nothing but accuracy in reverse, it's rather easy to figure out. 2 AGI = 1 evasion, 2 evasion = -1% to enemy accuracy. When evasion = enemy accuracy you will have a 25% evasion rate (monster 75% hit rate). You don't get LCF so there isn't any +4 evasion / level bonus.
Level 97 A accuracy 403 = 382.7 [382] accuracy
Level 99 C- evasion 368 = 351.2 [351] evasion
EBII +22 evasion
So naked your looking at 373 evasion vs 381 accuracy, or a 79% hit rate from the monster prior to AGI vs DEX. It takes 4 AGI over the monsters DEX to reduce it's hit rate by 1% and you have 56% worth of hit rate to go through. 56 * 2 = 112 worth of +evasion required.
And you want to say, with a straight face, that your wearing 25% haste while having that 100~112 worth of +evasion equipped and fighting these level 95~97 monsters.
