I'm used to the Pokertracker stat Went To Showdown (WTS).
In Elephant I noticed that there is a similar but maybe not identical stat: Went To Showdown when seen flop.
Is it only a matter of name or is there a difference in the way the values are computed?
As a motivation example, the article in the gold section about Pokertracker stats uses WTS. I'd like to know how i can fill the gap between WTS and WTSwsf - if there is a gap at all.
thanks
