For Gramazeka (HO2, AO2, BRH-0, EBJ2)

[Cacarulo]

I do not want to open a separate topic, for this I will ask my questions here for Kakarulo. I'm interested in comparing several systems at different spreads. Let it be 6 decks, pen 4/ 6 , spread 1-20 and 1-50.

1. AO 2 vs Hi Opt 2.
2. EBJ 2 vs BRH 0.

My academic interest is this - at what spread would AO 2 outperform Hi Opt 2 due to its more powerful BC? And due to what BRH 0 outperforms EBJ 2?

See post by BRH

He put BRH 0 higher than RPC.

 Here are the answers to your questions:



 Sims conditions: 6D-S17-DOA-DAS-SPA1-SPL3-NS, 4.5/6, R22 plays, 50 billion rounds each, play-all, heads-up.

                         1-12         1-16         1-30         1-40

 Hi-Opt II/A    25.53         29.74        36.91        39.34

 Omega II/A    24.67         28.80        35.84        38.23

 Hi-Opt II        21.89         25.68        32.15        34.33

 Omega II        21.11         24.82        31.16        33.29

  
2)

  

                        1-12         1-16         1-30         1-40 

 BRH-0          22.77         26.79        33.71        36.07

 EBJ-2             22.53         26.50        33.35        35.69

  
The problem with EBJ-2 is that it counts the nine. While this improves BC, on the other hand it decreases IC and PC/PE.
 
BRH-0

  

 BC = 0.9799

 IC = 0.7852

 PC = 0.7774

  

 EBJ-2

  

 BC = 0.9854

 IC = 0.7462

 PC = 0.7713

 
About BRH systems

 
BRH-0 is actually Red-7 or Double Red-7 and can be played in both RC and TC modes.
In fact if you look at my CAC/71 system you will see that by doing (2*pc+sc) I am using DR7 in TC mode but ONLY for betting.
In EBJ-2 the idea was to increase BC by counting nines, but as I said before, this decreases IC and PC/PE.

BRH-I is HALVES but not counting nines. The same problem occurs here as with BRH-0 and EBJ-2 and that is why BRH-I outperforms HALVES.

BRH-II is ZEN with an side count of aces.

Enjoy!

 Sincerely,
