W$SD with Highcard

[MoDOH]

was going through my PT database last night as I do every now and then. I Checked out the misc Stats Tab and clicked the "Show only where hands were not folded" box. I then noticed that my W$SD for High Card was a measly 21,18%. To be honest I don´t know what a good number should be on this stat, But it looks really low for me... Am I calling down too often with High cards?
since I think that this number should be correlated to Folded to river bet% i am including that one too
folding to river bet%=37%
