where is this mentioned and explained?

how is that fair or correct?

i have been renting Steem Power for months without posting if an average is in place shouldn't i be receiving bonuses now for all that time?

my account shows this feature has problems since i give over double the amount i get and this is assuming 50% of my voting at 100% i would be giving 4 times the amount i receive.

i dont see how making a new post and waiting 7 days to see would show anything but waste my voting i have 7 active posts and % i have received have already changed since renting 5k sp,
