CVData : Unbalanced True Count

[Phoebe]

If you are true-counting an unbalanced strategy, set unbalanced true count. The true count will be calculated by the formula (RC-pivot*(decks played))/decks unplayed. Unbalanced true counting is supported for both simulation and index generation.

As pivot is point where advantage is know, I don't understand.

That's just a back of the envelope estimate. Basically, the pivot point is the sum of all point values in a single deck. 2 for Red7, 4 for KO.

For KO or REKO, yes.
But for Snyder's Red 7 it's 0.

Never mind, I will not use unbalanced TC. Was just by curiosity.

Another strangeness.
Red 7 (unbalanced), with 1 for red 7 give very different index that 0.5 for all 7.

For instance, 9 vs 2 is 12 instead of 4

Depends on exactly how you define pivot and what the IRC is. The first edition of Blackbelt defines the Red7 pivot as 2. The second edition says that you start the count at the pivot times the negative of the number of decks, and therefore, the pivot is 0. Which is a bit confusing as it says the pivot is 2 so adjust the IRC to make it zero. CVData internally actually has three definitions of pivot, Pivot, XPivot, and RealPivot depending on the use. In the case of the formula in the original post, pivot is the unadjusted, single-deck pivot. 2 for Red7.

Perfect explanation. Thanks.
What about other issue ? More annoying as I don't want count 0.5 for all 7 (something to do with SP21)

It seems that indices are shifted by +8 (in 6 decks)

The Unbalanced TC indices for Snyder's Red 7 already exist and can be found on Arnold Sndyer's website.

Thank you.
Interesting. Indices are same as CVIndex. Well.
I guess spread 1-4 relates to wonging.
