You should never be close to "riding the clutch" as you upshift at 5 or 6k RPMs. SRM should have no impact on when or how long to "clutch" during upshifts. SRM during upshifts just ensures the RPMs are kept steady, and is only noticeable if you're a slow shifter.

- Depends on how you're downshifting. If you're downshifting to a stop, speed change, or upcoming turn, there's no need to give it gas until necessary (speeding back up). SRM will make the downshift smooth by keeping RPMs stable during the shift, instead of a normal car where your RPMs may jump from 2.5k to 4k during a downshift, causing an uncomfortable jerk.

If you're downshifting to speed up or get out of a sticky situation, the clutch and gas pedal movement should be similar to an upshift...quick and smooth.
Ok what about low speeds. if i am shifting at lower rpms like around 2-2500, on a local street, only getting from gears 1 through 3 between stop signs, should i release the clutch slowly and smoothly, if the revs are matched perfectly do i still need to do this? or should i just drive the car exactly as i normally would if it didn't have srm.
