I wasn’t aware in your previous posts that you had it miscalculated. Perhaps you valued haste higher because of it? Hmm. Still going to lurk on your blog :) I wanna know where you’re going with this.

Anyways, an interesting point: various sources of haste stack multiplicatively for your cast time but it doesn’t stop there. When checking your throughput you get:

new hps = (old_base_heal/old_base_time) (1 + haste1) (1+haste2)… (1+crit/2) etc..

So in terms of throughput, your sources of haste aren’t just multiplicative with eachother but with all factors that increase your throughput (including SP). As they are a product, the largest product can be created by balancing the stats (not just A > B but A/B = best ratio). And this balance is quite easy to work out! Since all your throughput stats gain equally from borrowed time & enlightment, you will obtain the same ratio whether you include them or not. You can work out the balance between haste, SP, crit etc without BT and Enl.

(Unless you hit the softcap)

Maths can be fun, no? :)

So, in fact, it hastes 2 spells. Your PW:S and your next spell. Very nice :)
