September monthly bonus has been sent by Stake today. Surprisingly, I have received less than $200 with almost $400k wager. I had received more than $100 from the previous monthly bonus with $85k wager only. My gameplay activity is same as it was in the previous month. I have played in-house games, slots and placed bets on sports event too. Didn't expect such low bonus amount from the monthly

It's really beyond my expectation because we think you will get more than $300 but will it be possible because you got profit in your game last month? we know stake has applied different formula for bonus since few months ago.
By the way how much is the base bonus for Platinum 3 ? I am platinum 1 and my base bonus is $50
There is no such thing as a base amount. My platinum 2 account got 12$.
So your base amount is $12, assuming you didn't play.
When someone says he has base 50$ for plat 1 and I have 12$ for platinum 2 you cannot talk of base amounts, my level is higher so my "base" should be higher obviously.
Yet another smart post from you. Business as usual.
It seems like the base bet is not based soley on VIP level, but also recent action.
A plat 2 that wagered $6k over the past 6 months is likely going to have a lower base amount than a plat 2 that has been wagering 60k a month for the past 6 months.
You claimed a couple months ago that you don't play at Stake any more. If that's still the case, and you got $12, then $12 is the base amount.
