What environmental factors would change the lengths of the lanes?
- zo1 10y agoThe concrete of the pool being hot/cold... It could, theoretically I guess, cause it to contract/expand by a non-insignificant amount.
- vacri 10y agoConcrete on a footpath gets slots made every step or so, to prevent cracking from heat expansion. It's hardly surprising that concrete the length of the pool could have a centimeter or so of wiggle room.
- bmj 10y agoFrom TFA: (Attempting to construct a concrete pool to any tighter a tolerance is nearly impossible; the effective length of a pool can change depending on the ambient temperature, the water temperature, and even whether or not there are people in the pool itself.)
