Bekele would have run 2 seconds faster if:
-His singlet was 2 inches shorter. The extra fabric was a waste. Weight and aero-dynamic penalty.
-if Berlin didn’t make him wear 2 numbers? Front and back? The aerodynamic drag had to be at least 2 seconds.
- shorter socks if his socks were just a bit shorter his ankles would have been a few grams lighter.
