SRM upshifts question

[PaulNYz]

So SRM will hold your revs at the appropriate speed to match the wheels when upshifting.

When on, are you supposed to get back on the accelerator and add a little gas when releasing the clutch like when normally driving with SRM off?

Or can you just release the clutch all the way and then get on the gas since the engine is at the appropriate speed?

It seems to be smooth when SRM is on and you release the clutch all the way before adding gas during upshifts.
