hello whats up with votes to account?

I've rented over 5k Steem Power which makes my shadow rank 9.2 and each 100% vote $0.19c

yet only receive votes worth 8.8% from shadowbot members and author rewards for a week are only $4, off which I've up voted $1 being $3 in rewards and my contribution assuming the 50% minimum amount of my voting is used = $6.3 if i put 100% voting would by $12
