I noticed that pool updates related to owners, pledge, margin, fix cost take longer to become effective than simple delegation changes. It seems that it takes at least one more epoch to become effective.
For example, when I add an owner it shows up almost immediately in the owner list, but does it already count for pools pledge?
A) When I add an owner can I increase pledge at the same time?
B) Can I remove an existing owner at the same time as I add a new owner (provided pledge is met)?
C) I know that pledge is checked before payout. When exactly does that happen?
D) I assume that pledge is a property of the pool and not of a particular owner, right?
Is there perhaps a section in some spec that describes this?
