When teams are comparing theoretical speeds, I think it makes sense to sense to use "geared for" assuming that means free speed. This way frictional estimates don't affect the number. This is essentially the rollout ratio times a CIMs free speed.
Any other number I think is only valid if actually measured, or from a team that has measured several of their similar drives and has decent enough friction parameters to estimate future drives.
