Very good question Stryker! The speeds were originally developed for the Tour Master and Legend. Note, this is only designed to give you a starting base. Personally I use the Daytona, as a legend a flat putt is about 1 to fast but as a tour master it was just right. I have learned to adjust my stroke. Further I utilize the early/late putting method, if you do not utilize this approach it would be hard for me to tell you where to start, if that makes sense. I would suggest you use it for a while and you will figure out where you need to be.
