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.
You are correct and dev is not. There are a lot more blocks per day because of PoS, not because of hash rate and popularity increase.
Since PoS has its own difficulty, it is not following the path of PoW.
As a result there will be less PoW blocks on overall and more total blocks per day.
So as an example. This coin targetspacing is 60s, which in theory leads to 1440 blocks per day. In practice there are way over 1440 blocks per day. Actual numbers may be close to 2000 blocks per day or even more.
There is no way to calculate how many PoW blocks there will be generated each day, but looking at the blockchain i could take a wild guess, that we get around 1000 PoW blocks per day.
Hopefully it answers your question.
