OP, could you elaborate on how exactly you ended up with $4400? It would be interesting to know the bets / payouts involved, as well as how much of your own money you had to temporarily deposit (you say $2000, but it seems like for each bonus in the screenshot it’s necessary to deposit an amount roughly equal to the bonus amount).
Also, you say six bonuses and $5800, but I only count five and $4800 in the screenshot.
In this case BetMGM seems to be negative EV. In OP’s example above, if the $1000 of site credit is only worth $800 or so, you have 1% chance of +$1000 and 99% of -$200.Edit: bad arithmetic on my part here, it should be 1% of +$99000, for total EV +$792.
