I suggest not increase scores after winning AI-bot, only level recovery (novice => amateurs => professional).
Me offensively seeing how bag-fighters increased on top.
There's a neat thing that amateurs are doing at the moment (I found out by accident once). They lose to the bot and the bot's ranking goes up, usually into the top 10.
Then, they beat the bot 2-3 times in a row and increase their amateur ranking without fighting another human being...
