Shutter speeds faster than 1/100 were initially assumed to be unnecessary, since camera responds to shutter command slower than that and the impact of faster times on total shooting time is negligible.
But shutter is also used in the zero-motion calculation (for acceptable angular velocity), and 1/100 is slow for long focal lengths (300-400-500 etc) so it causes unnecessarily long delays waiting for the platform to stabilize.
