I have about 6 flights on the pack, all flying P-07 and pulling around 4000-4300 mAh out of them. Power wise its hard to compare since I dont have any brand new original 5000's around and its been a while since I last flew a fresh extreme pack. However as best I can recall they are at least similar and possibly better power wise.

The best part is the pack seems to have a little flatter discharge profile more like the 5300's and holds balance far better than the originals. I did not get good life from my original extremes I think mainly because with those discharge levels they would go out of balance quite severely at times. Anyways I will see how they hold up from preparing for the WC's and let you all know.
