Proper Use of SP Tool

[geddy1001]

Hi folks, first off, I didnt really know which thread I should put this under, so figured Id start here. Ive been using the SP Tool for a while and totally love it. I probably should have posed this question a while back but was never near my computer when I thought about it. ANyways, since I use the SP Tool alot, I wanted to make sure Im "properly" using it. Obviously the bolded green are the best Starts of the day and the negative ones/red not so much. All my leagues, both roto/Points are 12 team mixed, so I use the guide for that BUT I was wondering, is there a best practices of where the "cutoff" rating is for 12 team mixed? Anything below .50? .25? I just want to make sure Im being as correct/optimized as I can be when using the tool. Thank you!
