Whether a figure is inside the difficulty ceiling at this tempo.
The ceiling is measured against the closest pair of onsets the figure asks
one player for, which is the thing that actually stops a hand — so the pairs
are counted within a stream (the limb, else the voice) rather than across the
whole kit, because a hi-hat and a kick a sixteenth apart are two limbs and not
one hand playing twice. A figure that fails is rejected — never quietly
simplified, because a simplified figure is a different figure and the caller
asked for this one.
