> without giving the standard deviations and nobody is outraged!

I agree with that! I was just swallowing my outrage :D

> if the standard deviation of each of the three experiments was around 1 cm, it would be troubling

That would be very curious though! These are animals not robots :D The only way I could imagine them to average that small standard deviation in the distance moved if we paralyse (or almost paralyse) them.
