May be i know the reason that due to multiple bid you received because you did not vote so long period say 8-10 hours or more. After that you vote all received bid in same time, that why we received small upvote.
This is not due to the price feed. This is becasue your bot not voted for long period and then voted all bids at same time. They sent bid for different times but voted same time by you, that's why we received less upvote. This is the fault of your bot.

You received multiple bid from different steemians as above mentioned screenshot 1.75 + 3.0 +1.75 = 6.5 steem for due to long period. Then you vote according to this 1.75 / 6.5 = 26.92% vote, 3/ 6.5 = 46.15 all steemians same time, so we received less vote.
