Thanks for the friendly tip, let me give you a more useful one. You need to synch spirit shell with AA, not so that they land together but so that you can use AA 1.5 times per minute. You use spirit shell to stack before a big hit, then after SS ends you instantly pop AA so that you can get a boost while topping the raid up then you have to restack and reuse AA quickly before the next spirit shell. After that you stack again and use quickly the stack and refresh evangelism just before spirit shell so that you start the cycle again. This is for maximal sustained HPS. For burst healing big raid wide hits you need to make sure that you can activate AA the instant SS expires. So that you can stack extra aegis and have extra oomph for healing up the raid after the big hits.
I was one of the people who contributing to getting the exact formula for spirit shell. You can find it on the EJ forums, but I also posted it on the beta class forums. With 6.36% crit and 30.41% mastery ss-PoH heals for 24% more than normal PoH. For Gheal and other direct heals it is 33% more, but PoH is the one that matters for aoe healing. This does not change too much for a relatively wide range of mastery and crit values. If your values dont match this then the most likely source of error is failing to properly calculate the contribution of aegis, mastery and crit to normal heals. For example on beta PoH heals for ~18k according to the tooltip, but if you add aegis, crit and mastery its actually 27k. Spirit shell PoH is 34k
Here is an example of perfect synching on elegon:

I am hitting 58k, but that is only because we are practically 3 healing it. Even so this is at peak and with heavy mana expenditure. He was bugged this try so we could not get into p3, however from past experience I can tell you I would finish that run at roughly 45k. With 5 healers I am in the 35k mark. Here is the same as holy but this time with 5 healers and for essentially the whole fight.

The monk above me was below me when we entered p3. He just went all out and built the lead you see in under 2 minutes.
Here is a recent example from blade lord in the heart of fear. I took a screenie in the middle and the end:

This is a great fight for disc, since it is very bursty without much sustained aoe. Disc is pretty much at 40k. The shaman hit 50k in over 60% of the tries.
The values I posted are what I see ppl doing in LFR right now on beta. I know I am not under-performing because I am pretty close to the theoretical maximum throughput, given the nature of the encounters, and so far no other disc priest in LFR has come anywhere close to me (which we can expect since its LFR).
FYI I was in the top 20 disc in WoL for most several fights on normal and hc DS before they started nerfing it. On warmaster I am still rank 20 disc even though I havent done normal warmaster for a very long time: worldoflogs.com/rankings/players/Dragon_Soul/Warmaster_Blackhorn/25N/Discipline_Priest/?page=1#p-15552457. On the first week of DS release, I was in the first page for every fight and was briefly rank 2 disc on Madness. I may not be the best disc priest eu, but you can bet I know I thing or two about maximising throughput.
