VDOT Calculator updates for Jack Daniel’s long runs and ultramarathon race prediction

I've made some changes to my VDOT Calculator
  • Fix bug in weeks 19 and 21 of “Jack Daniel’s Plan A” long runs. Those weeks have the lower of 22 miles or 3 hours, but the calculator was using 3 hours at marathon pace rather than easy pace.
  • Change the race time predictor for races longer than 50K. For these races, the VO2max calculation is done to predict a marathon race, then the Cameron model is used to predict the longer run from the marathon prediction.
