And also, I do think Jakob can run a very fast 5000, though outkicking high 12:30 and low 12:40 guys in a 13:15 race is not proof of 12:35 5000 ability, which is what many Jakobites have tried to tell me on other threads, his 7:54 2 mile is indicative of fast 5000 potential.
Mo Farah beat faster guys than him at the olympics, though that was in slower races than both his and their PRs, there is no way him beating them was indicative of him running anywhere near their PRs ever.
