It`s not! In fact there are of course outliers like Yuki Kawauchi 2x 1:02:18 + 5 min = 2:09:36 , and his best is 2:07 :27 , and we get only 2 x 1:02:18 + 2: 51 min !! = 2:07:27.
OK peabrain, let's wait for Kandie to run a 2:00:04 marathon.
And where was Tergat's 2:03?
Even better, where is your athlete Sammy Nyokaye's 2:09? He has run 1:02:13, so according to your idiot logic he should have a 2:09:26 marathon time but he has run 2:14, 2:14, 2:18 and 2:19.
I know the answer. It's because he has an incompetent coach - you!
However, there are a significant number of 101 Japanese half marathon runners who have ran 207 which conforms to the double plus 5 rule proposed by JS.
I think runners who are able to double their half marathon time and only add five minutes are obviously at the very top of their game and superbly fit.
For slightly lower level runners I think you are correct with your double +7, approx. The Swedish guru would however argue that those runners who run double +7 have not achieved their potential and he may have a point. We can see the same thing with 5000 10,000 m where the rule is normally double the 5000 time +1 minute but some runners are better than that and others are worse. However, the typical 1320 type runner is actually a typical 2740 type runner as well. So the rule is actually pretty accurate.
There is no hard and fast rule. Kawauchi is obviously an outlier as well, and looking at his best times on the track as well, 14:00/29:00 running a 2:07 marathon is absolutely phenomenal and probably unprecedented.
