Just for clarification, there is no regional aspect to the grades. Also no event basis for grades. We do showcases that might not have a single 10 grade. We do showcases that will have as many as 100 10 grades. i.e. National Showcase. A 10 is a 10 in Calfornia or Florida or Canada. Same goes for a 6.
Also the scouting scale displayed by JP I details the actual MLB averages. So a high school kid throwing 90 mph or a 60 time of 6.9 is already a 5 or 50 on the MLB scale without any projection. On our scale he would grade a 9 at those tools. Then projection could easily give him a 10. The grade associated with a scouts view of a players potential is called OFP. So there is a current grade based on current level of that player, 4.2 HTF time = 5 or 50 current grade. If the scout sees some potential that the player might get faster in the future, he could upgrade that grade. In the end all the numbers are added up divided by the number of skills and the player ends up with an OFP score. Overall Future Potential. Once again, an OFP of 50 is MLB average (Future potential)
