That is my assumption as well, but another forum put up some stats @ Daytona with Nascars and they were getting 30 laps on softs. More testing, but maybe there is a lap cutoff .... whereas anything less than, say, 10 laps, and its the old high-wear model. Over 10, its considered endurance, and new model is in effect. Just shooting from the hip on that one ....
Its also mentioned that draft is functioning in free run mode
I guess I need to get online ....
