So what if we modify this a little?
Consider this:
1 [B4B, botd, GK, 16] 2 [19]
3 [22 ] 4 [GK, 15]
5 [GK 8] 6 [Fit in one more GK before buff runs out, no 4th proc]

We have not achieved necessarily MORE GK's, but we have rearranged how they are organized. We have three within close proximity to each other, then only one near BotD's activation. In addition, we purposefully consume the rest of the buff on the rotation before we will reactivate it.

Why? Well, first, let's just look at the numbers really quick. Average as I did before, sans buffs:
2100 + 2100 + 1900 + 400 = 6500 [Total potency, 200 less as one less 4th proc]
6500 / 29 = 224.1379 [One less GCD though...higher potency per GCD! Whoa!] (Continued in hopefully last post)
