Manually calculating thumbs up/down isn't hard, assuming you don't break top 10 and you start off each submission with a fresh electrum earned count.
Just take total electrum earned, divide it by base electrum per win (9 for gold). That's how much you would've had if it was only thumbs down; then subtract number of wins from that number to get # of thumbs up, then subtract # thumbs up from total wins for # thumbs down.
