This was already mentioned in different thread
I have two different race predictions, at two glances: Performance and Primary race
Both shows my predicted Marathon time.
Both are different for good 5 minutes.
I know those are just numbers, but at least there should be some consistency in algorithms. I do not care which one was used, in my opinion both are wishful thinking for me.
And second thing. Performance is calculated on VO2Max (I guess). Why on earth few last days before my Half marathon predictions are jumping up and down like bungee?
At least trend is consistent but why those sudden jumps?
