Exactly.

If you rev the engine to 2000 rpms, and smoothly slip the clutch out (or, as smoothly as a beginner can), you've got maybe 20-50hp and 2000 rpms grinding the clutch against the flywheel. That sounds like a fair amount of wear for every single launch.

If the engine is at idle, and you smoothly engage the clutch without any throttle, you've got around 600 rpms and 1 hp.

So, you're right that it's not *actually* zero, but it's near enough to be called zero.
