You mistook what I said. The payout wasn't 47 cents, it was $0.47 in post rewards. The payout was 0.472.380.5SBD + 0.470.53.04=$1.27. The amount of payout possible is limited by the steem power of the bot. So even if you pay more, you can get a max vote of $1.27.
Think of it this was, A bid 1SBD, B bid 2SBD and C bid 3SBD. Then of the 100% of the bid is divided into 100%/6 for A, 2100%/6 for B and 3100%/6 for C. In your case, your BID would have resulted in negative ROI of more than 15%, so it was moved to the next round. It is usually expected that people will bid according to the vote power and not send such high bids.
Please also note that all bid bots are paid promotional services, i.e. They are providing a kind of advertisement for your posts. People aren't expected to make money off it. Still i reiterate i will try to return some part of your bid soon.
