I am working on calculating TPR, and got lost in the math.
Let me start with EPR
2nd call 45.3 the EPR is 92 - 1 1/2 BL = 91

LPR
1:11 time is 71 sec. - SC 45.3 = 25.7 is LRP 81
plus 1 length ahead= LRP (FFP) 82

If Tres Belle was a SP why such a good EPR and low LRP

TPR is 174

any help would be great.
Thanks
Don
