the issue with WT is that it is one category trying to indicate 2 things
1st somone who is liable to fold if bet at on flop
2nd somoene who is likely to have the goods if it gets to showdown
You can see why low WtSD% is indicative of both to some extent. We would like to split this category into 'good WT players' and 'bad./weak ones' but we don't have an extra category free..
For the moment what I am doing is having W$SD as one of the stats permanently on display and being sure to check it when I see the WT icon. Then I know what type of WT player we are playing with.
If you want to make the icon indicative of just the winning WT Players you can use the follwoing rule (which was AP10's original suggestion)::
Went To Showdown % is less than or equal to 18.00
Won $ At Showdown % is between 65.00 and 99.00
Personally think there is a strong case for pushing the W$SD figure up to 67% here so you don't get a lot of 2/3 players rated in here.
