Those numbers seem cherry-picked to put Coe .02 ahead of a corrected Cram. They don't add up.
Coe did run close to the line of lane 2 a good deal of the race, sometimes inside. Since they run in lanes the first turn, the maximum from running square in lane 2 would be estimated at 6.8m per lap or 10.2m total for three turns. He's not always in lane 2 at .3m from the line. Sometimes he's in the outer part of lane 1. It looks more like 9m.
Cram was outside a bit less but usually on the outside of lane 1, not far, in other words, from where Coe was.
Cram's was intrinsically better. He was on the outside of lane 1 for turns 2 and 4, meaning somewhat close to 3m extra on each turn, closer to 6m total certainly than 4m. He is not drafting on those turns. 1:42.11 if 6m extra.
You don't know what you're talking about.
If you run an entire bend on the line between lanes 1 and 2, that is 2.91m extra. If Cram runs in the outside of lane 1 (which is what you have written), and he was a good 30cm inside of the line, that cannot be 3m extra per turn. He would have to run, on average, an entire bend with both feet in lane 2, albeit just over the line, to run 3m per turn. He ran 4m extra in Zurich 85, and was not near the line between 1 and 2.
Coe was often in lane 2 on the bends in the LA race. You have to work out an aggregate over the duration of the entire bend.
Running 3 bends 'squarely in lane 2', by which I presume you mean the middle of the lane, is 4.8m extra per bend. That's 14.42m extra over 3 bends, not 10.2m!
The radius is 36.8 and is taken 30cm from inside of lane 1. Each lane is 1.22m wide. Therefore the radius of running in middle of lane 2 is 0.92m (line with lane 2) + 0.61m (from line to middle of lane 2) = 1.53.m, or a radius of 38.33m.
Coe only needs to have run , on average, 14cm wide of the line between 1 and 2, to have run an extra 10m.
Looking at the race he is always either on the line or just outside it. It was nearer to 10m extra than 9m.
Hey...you do that mathematical stuff about as good as calculo but without the bad attitude. Appreciate you explaining it in a civil way. ?
