reading the kinds of possible explanations you pointed to moved me to have questions about stake:

Three types Of possessions that can stake emerge:

1. unlocked
2. locked up rewards
3. locked up non-rewards

one: can you say what This separated camps is for? these "locked up" are all complicated. and What is the reason rewards are different behavior?

two: in 9.1.1 it seems that camps 1 & 2 each age according to some laws ONce they become "mature" -- and they become "mature" after 512 blocks. is it correct though that camp 3 (locked up non-rewards) has it that it matures in some 8 blocks? can you give a clue what is the reason for this very fast becoming "mature" here?  It seems to lack stability in principle since you possibly can stake every 8 Blocks with the same locked up non-reward?

three: in 10.1 the idea of "stake modifier" is being discussed there. it seems that at each block the stake modifier for the next 256 blocks are known, as well the fact the next 256 part is known. I Can project a problem. the locked up non-reward can be used to stake 8 blocks next and I can known the stake modifier for this next 8 blocks. now how to solve this problem?
