Norm: Cvdata: How to?

How to add custom fixed payout bonus in Cvdata?

Say, in normal blackjack game: 6-7-8suited pays 25$ extra
or 6-7-8 pays 0.5bet extra capped at 25$ max.

How can I find EV of the game?

I've tried setting custom bonuses which have both variable and fixed payout.. Even fixed payout is relative to original bet.
I tried looking at spanish super bonus which is usally fixed at 1k,5k. But I've noticed that super bonus template have created payouts for fixed as 197:1

Is there a way I can select the upper bound in those custom bonus? or Can set fixed payout irrespective of my original bet????

Fixed bonuses are specified in number of units. It has nothing to do with how many units you actually bet. In other words, if you use a $5 unit and your count calls for a 5 unit bet ($25), a variable payout of 4.0 would pay 4x$25=$100, while a fixed payout of 4.0 would pay 4x$5=$20. Doing half bet with a cap is something that I don't think the software can support, however I think you can get the data indirectly by looking at the tables to see how much you made on the bonus at each TC and adjusting those numbers by the relative bet at each TC. That would help you fix the EV numbers, and it won't have much impact on the variance anyway for this particular bonus, so you would be safe to assume the variance stays almost exactly the same. The SCORE is proportional to EV^2, so if your adjustment results in increasing EV by 10%, your score would go up by 1.1^2 = 1.21 times. Similarly, if the EV decreases by 10%, your SCORE will change by a factor of 0.9^2 = 0.81, or a 19% drop. The adjustments you'll make to fix the payout cap issue with that particular promo shouldn't change your numbers that much. As far as the upper bound on this bonus, if you are betting at least $50 so that you get a $25 bonus on any 678, suited or not, you will get a bonus once per 362.65 hands, for an EV of $0.069 per hand in addition to whatever your EV is for the base game.

Thanks for the response

I did figure out the EV by running two different sims and then using excel to get net ev at every count.. But i wasn't sure about RoR, I guess now I can have those numbers also. Thanks a lot for your help..

solution is posted above

ask qfit

By nynefingers that fixed is relative to unit size... I was assuming that fixed is always $$$$ or currency used, but nynefingers have cleared the doubt and I got the results..

Since you ran the sim both ways, here is how I'd approach RoR. I'm going to assume that the variance numbers were fairly close both ways, unless your betting level is reasonably significant. Pick whichever of the two sims most closely approximates the results you will actually see and use that variance. That means if you are a red chipper whose bets rarely reach the $50 required to max out the promo payout, then use the variance from the variable bet sim. If you use a $25 unit, you'd be using the variance from the fixed payout sim since you'd frequently be betting well over $50. If your betting level is in between, it's a judgement call, but you should be able to approximate your variance pretty easily. Using that number and the overall EV you calculated, you can use the RoR calculators built into CV to determine bankroll requirements, etc. To calculate SCORE, you will need the EV per hand and the variance per hand. EV per hand equals 1/100 * EV per 100 hands. Single hand variance equals 1/10 * variance for 100 hands. SCORE = (EV / SD * 1000)^2.
