My point is this - On say a 12 hour block, loyal miners will pay a lot for electricity.
A pool hopper comes in within the last hour and gets the same reward for a fraction of the electricity.
I do understand that we may find the block a little quicker but loyalty is not being rewarded here.
And my point is that a 12 hour block with ONLY loyal miners will became two 6h blocks (with half of your reward) if the pool hashrate doubles because of pool hoppers, so you will get the same amount of BTC for the same electricity used.
If you know when the round will end - use it for your advantage and jump to the pool which will find the next block ... or better yet play lottery if you can see the future, because that's the only way to know when the round will end.
Just to remind the situation a few months back - every time the pool hashrate approached 1Ph the pool luck was low and the newcomers got nothing by jumping in, so ...
It all depends on luck for a short period of time and is equal for a long period of time
