Remember AHOY said, don't expect too much

we don't know how they apply the formula to bonuses.
Just a reminder you may be able to claim a highroller bonus this week and also top VIP bonus yeah the total is probably around $500 and you can use it to reach new VIP levels.
Top VIP is not that high, especially when you are in profit. I had 450k wager in April with a bit of a loss and got 380$ top monthly bonus. He got less wager (so far) and a huge profit. So top VIP should be around 300$ at best. Since he doesn't have a host this question doesn't matter though since only platinum 4 players can claim top VIP.
About the other thing, they also take bonuses in account when calculating the monthly. That high wager month I had some good weeklies, some good reloads and maybe lossback and of course rakeback. That all pushes the monthly down a lot as well of course.
