Rhythm Doctor-related shower thought: because subdivision beats are placed and scaled to fill the area between the hit of a beat and the start of the next beat, you could use “swung” SVT beats to create subdivision beats that appear to run at a different speed than the rhythm that it’s placed in. A swung SVT beat with a “rea…dyget…setgo” cue-to-rest ratio would have faster subdivision beats, while a more abrupt “ready…getset…go” beat would have slower subdivision beats. In fact, fast-swung subdivision beats would be so slow that they couldn’t be completely cued before the first beat hit.

Here's a visual representation of what I’m trying to get across:

C = cue point, H = hit point
/ = active beat zone, . = resting

Balanced SVT beat:
C///H...C///H...C///H...C///H...

Balanced subdivision beat:
C/C/H.H.C/C/H.H.C/C/H.H.C/C/H.H.

Slow swing SVT beat:
C/////H.C/////H.C/////H.C/////H.

Slow swing subdivision beat:
CC////HHCC////HHCC////HHCC////HH

Fast swing SVT beat:
C/H.....C/H.....C/H.....C/H.....

Fast swing subdivision beat:
C/HC.HC.C/HC.H..C/HC.H..C/HC.H..
