A few things were missed in that stat weight quote above.

Accuracy Caps:

Ravana EX: 572+
Alexander A1S: 595+
Alexander A2S: 609+
Alexander A3S: 639+
Alexander A4S: 647+

Skillspeed Softcaps:
Maximum : 652
Minimum : 590 (which is recommended in the thread above)
I'd recommend giving the DRG thread a serious read when you're able.
