Reputation matters very little. It's ONLY Steem Power SP (Powered up) held in the account that is doing the voting PLUS what vote % that account used determines the amount a post will make. 100 accounts with only 15 SP would equal 1500 SP effective voting power that is worth only about $0.12. 1 account with 15,000 SP vote would be worth $1.20, 150,000 SP = $12.00 vote, etc, etc. Many users have a vote way less than $.01 so it would take hundreds of votes from these accounts to have a total payout of over $1. My SP is around 500 right now my, 100% upvote is only worth $.04. If I would of used 50% it would of been $.02.
Don't forget: ALL of these numbers will change for everyone especially when the market goes up or down considerably. Hope this helps.
Thanks a lot for your valuable reply
