Stat: Fold SB to steal x Fold BB to steal?

[eroock]

I wonna combine those two stats into one and I am new to custom stats. How would I go about this?

"Fold to Steal" is a built-in stat.
If you're interested in how it is built you can see the expressions in the Configure Stats window. (Tutorial: Custom Reports and Statistics)

Thanks. The formula looks wild. Is it an average or the product of both values?

[WhiteRider]

It's the sum of both actions (folding to a steal from both positions) divided by the sum of the opportunities (facing a steal in both positions) - i.e. it's a pure percentage of the times that you folded from either blind position when facing a steal.
