How many hands a stat based on,can this information be shown on HUD?

[HHLWX1]

I don't mean the target's total hands,but the hands one certain stat based on.For example,I have one person's 3Khands,I have seen that his Fold to my turn CB in 3bet pot is 75%. But can I give this stat much confidence?Maybe not.Because I don't know how large the sample is.Maybe in this situation,there're just 4 hands.Then his 75% fold doesn't mean much.
So,I want to know how can I get the hands'amount a stat(especally those don't happen frequenly,like Fold to CR river) based on.Can it be shown on HUD or popup?

If the stat sample is below 100, a (xx) should show next to the stat up to 99. Once it hits over 99, the brackets disappear. There is no option to add total sample size to a stat permanently though.
