There is a Skill Speed breakpoint for DRK at 1116 which gets you a GCD recast of 2.38. If you achieve this, you get a 7th GCD under Blood Weapon. This translates into a gain of 67 potency/minute if you execute every BW window perfectly. One reason for using the Genji chestpiece (DET/SKS) over the augmented chestpiece (TEN/CRT) is to reach this SKS breakpoint. There are alternate combinations of Genji pieces that can achieve the target without the chestpiece, but the Genji chest is a pretty efficient way of doing it (giving 253 SKS) without having to give up the augmented belt and boots (DET/CRT), which together cost you 236 SKS. The chest offsets the cost of this.

There are higher theoretical breakpoints for a 4th GCD under Delirium-BW and an 8th GCD under BW (2184 and 3119 respectively), but these are too high to be relevant in practice.

Wait, what? You can do 7 GCD Blood Weapon with 0 Skill Speed, even without delaying activation.
