System indexes

[BjFool]

i find it somewhat strange that Hi-opt II system indices coming from 3 different sources would show , on certain hands significant differences.

sources: 1)Cardcounter.com 2)Casino Vérité 3)BlackJacK Pro

exemples:

Hard hit

13 vs 3 (-3)BlackJack Pro

13 vs 3 (S) Mayor's site

Hard double down:

9 vs 2 (+3) Casino Verité

9 vs 2 (+1) BlackJack Pro

8 vs 6 (+3) BlackJack pro

8 vs 6 (+4) Casino Verité

and that's just to name a few, there are many more such differences. Anyone care to explain the reason for this? It seems to me that those TC numbers have a great impact on the playing strategy.

thanks in advance

It could be different programs used or slightly different rules. If you want to be safe use the highest number or verify the rules and which program you are willing to trust.

Re: System indexes SIMPLY STATED...

SIMPLY STATED - there ain't no such thing as 'precise' indices (i#s) - #decks, %pene, generation-method, and other factors will create different i#s for the same hand - which is a good reason to learn grossly-rounded i#s - regardless of which i#s you use they will produce the same results statistically - so use i#s that are the easiest to remember and the fastest to deploy. zg
