It's a 1/6th of a second foudroyante that can be stopped mid-jump. 1/100 is an arbitrary number, with different dial printing, it could be 1/20 or 1/1000 seconds.
It's probably a step up over a normal foudroyante, I'm not sure how accurate it is, since it dwells on the 1/6 spots longer than the others. Still very cool.
