This is just speculation on my part but:
With most of the hashrate being on the lucky pools the diff has to go very low in order to sustain the desired block finding rate which means that way more than 1 out of 50 blocks are lucky blocks.
I thought of this. If most people are mining on lottopools then if you switch to a normal pool with the lowered difficulty then this pool will find blocks 49 times faster and it'll balance out.
Also sorry for the mistake it's not Max PoW coins, it's the approximate max without accounting for lottomining. Clearly the supply will be a bit more with this many people lottomining
