I just saw this tweet: https://twitter.com/SmaugPool/status/1428010540711006218
Next epoch (285) should be great at 109% luck with 19 leader slots
At the time the tweet was made, epoch 284 was still in progress.
How is it possible that the stake pool owner already knows how many slots/blocks he gets assigned in the next epoch? Can this information be retrieved from the blockchain?
Also wouldn't this mean that one could always check which pool has the most blocks assigned and then switch to that pool for the next epoch?
