I think the H2P site said in the range 1.5 million effective dps to him during this 40-45s.
I was getting to a very similar spot. I found that if you just kite normally in phase 1, then in phase 2 (where you are trying to kill Raest) is just do a normal voidform. Get him down to 80 or 75%. He will then go immune again and his bro will chase you around. Finish off your voidform, pop surrender, get to 100 insanity and start going to town on Karem. With surrender up, you will be able to not only kill the hands super easy but also able to kite him. Karem should die once you get through about 2 hands (you can blood lust when 2nd hand spawns and you wont waste much of the duration) and you will start phase 4 with Raest up (this time at 75-80%). There isn't a time limit here, and with the 40-50 stacks built up with the tail end of lust and PI you should be able to down him no problem (and with much less stress).
I just think the 1 phasing technique requires almost perfect play around globals to kick out the damage while this strat is much easier (in my opinion). I switched from the 1 phase Raest strat and to this one and killed in 2 attempts lol.
