And you live in which country??!!

There ARE some games like that in the USofA, though not many.

4.5/6 penetration seems low. I only play when penetration is 5/6 or 5.5/6. Also isn't SCORE assuming the spread is 20 to 1?

4.5/6 is an standard.

The fact of the matter is that the system ratings of many reputable researchers do not match.

There exist a quite large number of settings in a sim and different folk make different assumptions. In one comparison, for each number of decks, I ran sims for different rule sets and for different bet spreads for each strategy, and then multiplied the results for each by the percentages of the different rule sets that existed at that time to create weighted results. So, for four charts for the four numbers of decks, there were 12 strategies, 104 penetrations, 2 bet spreads and 16 rule sets for a total of 39,936 sets of conditions. I then plotted them by penetration.


On top of that, you must select the number and type of indices, deck estimations, TC integerization, and when TC is calculated. And then still, when looking at what is the best strategy for a particular person, we must take into account ease of use (which depends on how that person's brain works), and flexibility should the player wish to join team activities or use advanced methods. My opening statement in this study was "There have been numerous attempts at comparing strategies, and all are flawed — including this one. "

Exactly. That is why I made it clear which were the parameters used in the comparisons:

1) 6D,S17,DOA,DAS,SPA1,SPL3,NS,4.5/6
2) Counting system A and counting system B
3) R22 plays (C22 with TTv4 instead of 10vT). They can be more as long as the same amount and the same plays are used in both systems.
4) Estimation of remaining decks can be to the exact card or to the nearest half.
5) Floored and EV-Maximizing (No RA) indices - (Full deck TC)
6) No burn card
7) 50 billion rounds each
8) SCORE or N0 (Optimal betting ramp and EXACT bets)
9) 1-12 and 1-16 spread

I think that's all. Anyone can use a simulator like CVDATA/CVCX or SBA or some personal one and solve the mystery.

Under these conditions, I have full confidence in the results of your simulations. But my question is, at what theoretical spread will EBJ beat RPC?

[Cacarulo]

Under these conditions, I have full confidence in the results of your simulations. But my question is, at what theoretical spread will EBJ beat RPC?

RPC beats EBJ2 at any spread. I've even tried with an spread of 70 to 1 and RPC still beats EBJ2.

          RPC        EBJ2
1-12    23.10       22.53
1-16    27.17       26.50
1-30    34.17       33.35
1-40    36.55       35.69
1-70    39.99       39.08

Hope this helps.

Thanks. But But how do you comment on this data?

You have to put it between [.CODE] ... [/CODE.]
without the dots in the words CODE.

Isn't by definition SCORE is calculated with full Kelly bet, $10,000 bankroll and 13.5% RoR?

[Cacarulo]

Correct.

[BJGenius007]

About post #45, these low RoR numbers are suspicious. Full Kelly has 13.5% RoR. Half Kelly has 1.83% RoR.

[Cacarulo]

Specifically Uns.won /100

EBJ 3.50
RPC 3.37

This is not SCORE. Even if you wanted a fair comparison, the ROR should still be the same. In EBJ it is 1.30% and in RPC it is 1.06%. It's like comparing apples to oranges.

This thread has a good summary of SCORE. And I think SCORE is the best tool to compare different counting systems.
