If you're thinking about fSTR, an extra point is either there or it's not (depending on mob VIT).
This is somewhat different from WSC where the extra point will also either be there or not but it's slightly different; sometimes depending on WSC% you'll get a point of WSC STR which you wouldn't get with fSTR. If you were to estimate fSTR in terms of WSC it'd be around 30% at level 75.
