for 10k it predicts 50 minutes, which is 3 minutes slower than my last time.

I used this to predict my 10k time based off my 5k. At first I was skeptical, thinking it was predicting faster than what I would do, but I actually ended up running faster than the prediction. Based off my 20:39 5k, I was to run just over a 43:00. I ended up running a 42:50 (this could have been a fluke, beginners-luck thing. It was only my second 10k of my life). In terms of per mile pace it was only like a second or so off, which I think is pretty darn good!

Might the predictor require some tuning ?

If I enter 21.0975 (half a marathon) and 1:20:10, the reply for 42.195 is 02:47:08.

According to the explanative text, I would have expected (1:20:10)*2*1.06 = 2:49:57?

The answer 2:47:08 looks like the coefficient would have been 1.0455 instead of 1.06?

(cancel and replace) oops, I missed the point! The formula is (^power)1,06 and not (*multiplied by)1,06.

What FrdricLN said, the formula is good, but it is stated incorrectly, it is to the power of 1.06, not multiplied by it as stated.
