The PoW phase is running faster that expected due to the massive uptake of the coin. Since the 19th May relaunch date we are now about 50% of the way through the PoW phase.
Remember the PoW will end at block 43200, after that mining will not be possible and the coin will go to 100% PoS
Is it possible that the PoW phase is going faster because PoS is constantly generating blocks?
If so, there will only be around half as many (depending on how the coin is set up) coins generated from PoW as you were expecting.
