When you set up a player in cvbj you are asked the following:
1. Select a strategy. I chose FELT
2. Chose settings and you get all of your rules etc
3. Choose 'attach strategy" and pick FELT F and to the right you'll see "Display Tables" which gives the indices
That is where I got the indices from cvbj

Sorry I didn't mean variance as you are assuming. I meant the count to vary from basic strategy or the index. My poor explanation.
