# Thread: Problems when customizing KO count in CV (Playing and Betting strategy numbers)

Why would anyone want to set counts to such high numbers? The difficulties in keeping a mental count would increase dramatically.

I think starting at an IRC of 100 is actually easier than at zero. You don't have to care about negative numbers and sign switches.

Starting at zero or in the negatives (as in standard Hi-Lo, KO and REKO) means that even when the RC is not hovering up and down, i.e. there is a slug of purely low or purely high cards, you must be aware that when the RC crosses the zero line, the absolute value of the RC is suddenly not decremented but incremented (or vice versa), which is a potential source of error.

Regarding the length of the spoken or thought numbers, counting "minus two, minus one, zero, plus one, plus two" can be shortened to "m two, m one, zero, one, two" , but you can likewise shorten "98, 99, 100, 101, 102" to "98, 99, hundred, 1, 2" etc.

The idea of starting the RC around 100 is btw. also seconded by literature, e.g. Fred Renzey in "Blackjack Bluebook II", 2006 edition, Chapter 12 "Mentor Count", pages 198-199, section "A 100 Counting Base" does exactly the same. I might have read this in additional books, too (have read about 25 such books), but can't exactly remember now.

Hi PinkChip, its my 2nd day with CV and the forum, and a week after reading KO Vancura/Fuchs. I've been using BJA and enjoy the site very much, but it doesn't teach or simulate KO, that's when I purchased CV and came across your post the same day. I start my IRC at 15 and Key Count at 31 to avoid negative #s, so I can appreciate your start at 100. I've been able to modify a KO game on CV to start my IRC at 15, but haven't been able to adjust anything else, even after reading your post a few times. Any direction, screen shots, or additional tips you might offer would be appreciated. (Of course, Norm and company as well, if they read this post).

Thanks, Liverpool-007

P.S. enjoyed your podcast interviews and Holy Rollers

I could very well be incorrect, but I don't think the PinkChip here was a member of the Church Team.

I think Arnold Snyder also referenced modifying the IRC to avoid negative numbers in Blackbelt in Blackjack. I use REKO 6 Deck Full with an IRC 30 and have never had to use a negative number. I guess it's possible, but I Wong out alot.

There is an example in the manual titled Playing Strategies (Quick Primer) which provides an example of how to create a KO strategy from scratch. You only need to modify the existing strategy. But, that should provide some guidance.
