Payouts Decreasing as Upvotes Increase Discrepancy

I noticed something frustrating, yet interesting in real-time today. I had a post with awesome photos with only 8 votes netting $3.03. That's OK maybe some more votes will come in. I had my blog pulled up on my phone and my wife standing right beside me just had the chance to read my post. I watched her click up-vote on my post and I refreshed  my screen and the total votes went to 9 but the payout went DOWN. This is not the first time I've noticed this. This was more of a real-time test.  What kind of messed up algorithm is being run. I know she doesn't have much steem power, but is the system programmed to reduce payouts if newer members upvote?  That is a terrible equation and harms the community and disregards new users' opinions and harms posters. It's already bad enough that newer users' votes sometimes don't amount to$0.01, but negative really!?  Overnight I have seen 83 votes valued at $150.xx and next day finish at 153 votes at$119.xx.  There is something discouraging going on with these calculations that don't make cents ;) (ha sense) Does this have to do with if then volume limits depending on if a higher powered steemer clicks then funds are taken away to go to them?
