Noob Question: Smooth up-shifting..

[2.7boxer6]

Hey guys,

Just getting the hang of driving my boxster but have a question about up-shifting.

My current shifting practice when up-shifting is:

1. get off the gas
2. engage clutch and switch into the next gear
3. come off the clutch with a tapering speed (slower as i get closer to the end)
4. ever so slightly depress the gas
5. finish coming off the clutch

My question is about getting on the gas before coming fully off the clutch. It makes it a lot smoother for me but I am wondering if an even smoother and quicker clutch movement would negate applying any gas?

Thanks.
