There's a simple way in RDSS to group horses by running styles using the "Win" and "ITM" checkboxes. For example, Earlies and Early/Pressers could be checked as "Win" contenders; Pressers checked as "ITM" contenders; and Sustained/Closers as neither, i.e. both checkboxes are unchecked. Of course you can group them anyway you want but that's what works best for me.
After going through the field of yesterday's Alabama and checking the appropriate boxes, here's the result:
After you've done your "by groups" analysis, you can go back through the field and reset the check marks. As far as the group headers, I ignore them. Yes, you can change them to read "Early," "Presser," etc., but that requires changing a configuration file, which makes something simple more complicated. (And handicapping is complicated enough.)
