There is NO way a middle-distance runner can run 10.99 FAT. There is a massive difference between FAT and flying, which is the way most distance runners record their 100m times.
Here you see Mo Farah, one of the greatest middle-distance runners of all time (3:28 1500m, European record) run a 100m race in competition. His time? 12.91.
He has recorded 100m fly times close to 11 flat/11 low, so the difference between fly and FAT is almost 2 seconds. This is in line with what Nick Willis, another insane miler/middle-distance runner said, his PR is like 11.1 but in a FAT he can't break 12.5.

Even Bolt is extremely slow over the first 10m out of the blocks. That's jogging pace that any LR user could run after being "on speed" that Bolt has in the first 10m out of the blocks, and he was one of the best acceleration guys in the world.
Rudisha, Lewandowski, etc. all can easily run a sub 16 5k. But I doubt they can do 10.99 FAT, unless proven in a race. Just way too many slow-twitch muscles, even for Rudisha who is a 400/800 guy.
People on LR are distance runners who got no clue what an insane effort a 10.99 FAT is. The main problem is that runners with a lot of slow-twitch muscles, and even speedy mid-d runners like Rudisha (and I know he got 45.5 400m speed) accelerate even more slowly than sprinters out of the blocks, in fact their acceleration is rather abysmal. Rudisha, Murphy, Brazier's etc problem is NOT their speed, it's getting to it out of the blocks. Their top-end speed is fantastic and they can run extremely fast in a flying 100, but blocks have a much larger impact than people here believe.
