Sorry for the confusion. I didn't understand what you meant by "what remains of their share after Bustabit deducts its share".
Both bustadice and bustabit now charge a 50% commission on net profits instead of a 0.25% commission on every wager. That means that bankroll investors have less variance now but also receive less EV than they previously did.
Sorry, "what remains of their share after Bustabit deducts its share" means 50% profit commission. I should have worded the question more appropriately.
When you say "bankroll investors have less variance now but also receive less EV than they previously did", did you run it past investors for their views? May I ask what the primary reasons were for the change? If you already had a working and highly successful formula on your hands alongside an excellent reputation why change the format when it might alienate some investors?
If you have thought this through and believe all investors will prefer this route then I wish you success. I see your reputation and the Bustabit/Bustadice reputation as something quite formidable in crypto gaming circles so hopefully investors will be go with the flow.
No investor would ever prefer this formula. This is essentially dropping our expected returns by 1/3.
