basically yes. if you look at a 1k games interval playing hypers @ 2% ROI and a 1k game interval playing regspeeds @ 2% ROI, you'll experience the same amount of moving up and down on average. tho ofc the hyper interval is much shorter coz the games last shorter

Thanks for correcting this JSpazz.
So the correct formula for the expected log wealth is
U = w*log(bankroll + stake - 2*rake) + (1-w)*log(bankroll - stake)

hi, so for example, if I have a bankroll of 100 and a roi of 10, i should play the 10s?
and if i have a br of 100 and a roi of 5, i should play the 5s?

While I read the first post I haven't read the rest of the comments, I have to say I disagree here, what your post doesn't cover is game selection and the impact of downswings, if your a player trying to move through the stakes you don't have the experience of playing higher and truly understanding variance and game selection. Fighting for lobbies to earn your place happens at low stakes so playing with 10-15bi at a higher stake because your roi would be higher there is absurd in some cases your roi will be way lower as you battle more regs.

I think having a large bankroll to take proper shots at stakes and not have to stress about constantly moving up down, seeing and dealing with bigger swings while lacking experience in variance is invaluable.

Some people may not get affected by swings earlier in the career as others in which case being v aggressive is ok I guess (not ideal imo) but if your one of those that your still learning and honest with yourself about your level of play when you dont understand spots meaning your not entirely sure if someone is beating you (that your are battling) then I would take it slower.

Props to OP for contributing to the community and his post may even be spot on, this is just my personal opinion.

Well, game selection, downswing, and other things you have mentioned should all be incorporated into ROI or winrate when we estimate them. For example if you expect to battle lots of regs at mid stakes like $100-300, you just have to take that into consideration and estimate your ROI accordingly.

Also, Kelly is mathematically proven to be superior to any other BRM when it comes to fastest bankroll growth. Like you said, when starting off the game and still learning it, a more conservative BRM might be better. But then again this is just a ROI problem, because if you know you can beat certain stakes with a good enough ROI, it's usually better to stick to Kelly or 1/2 Kelly than being a BR nit.

Personally I have used Kelly and 1/2 Kelly throughout my entire HUSNG career with very few exceptions and that just worked best for me, even though I had to battle tons of regs. At $100-300 turbos and normal speeds I expected to have 5% vs regs, which was 20-40 BI according to Kelly or 1/2. That meant I had to move down quite often, but that doesn't mean my BR was not growing in long term.

Cliff is, if you know you're beating the game and are eager to move up (and down too, whenever necessary), Kelly is the way to go imo, as long as you can estimate your ROI reasonably accurately. If not, it's probably better to fall back on a more conservative BRM.
