Say you get $133.33 in rewards. 75% goes to you, that $100.
According to that article:
50/50
$50 SBD = 43.187 STEEM
$50 USD = 12.968 STEEM
Total = 56.155 STEEM
So a 100% power would only be 12.968 x 2
Total = 25.936 STEEM
100% powerup only makes sense when STEEM > SBD and STEEM is close to $1 USD .
Only when SBD is 1$ or less on the exchange >100% pwup
I’ll need to have another read. I generally do 50/50 because SBD has a number of uses but was planning to do some 100% power up posts soon though.
I verified the math against previous payouts and against @rmorel's recent 100% power up. Now that I have some SP, maybe I will do a post on this. I need to figure out a nice way to graph this first.
