Clutchless Shifting, good or bad Options

[aww_shoook_em]

when I used to be into RSX's before, I remember coming across a media thread that had a video with clutchless shifting

out of nowhere, I asked my friend about clutchless shifting.. he told me, it kinda takes practice and its less wear-out for your clutch
and stuff.. now that Ive heard the positive things about it, I was wondering if there were bad things about it...

if theres like 2 things that are bad about clutchless shifting, then I wont trip about it.. but if it comes to more than 3+up
then Ima have to break the habit of it..

so 6gc fam, what would it be?? YE -or- NAY on clutchless shifting

(I'd rather not base this on polls because I like my information straight to the facts)

Am I doing it right if I ...

Rev through the gear with a steady amount of throttle,
gently tug the gear shifter towards neutral in a single motion at the same time as my foot smoothly comes off the gas.

Gently tug the shifter towards the next gear, as my foot gradually goes back down on the accelerator the engine sort of "sucks" the next gear into place for lack of a better term...

????

I've heard that this is better for motorcycle racing when perfected, would this technique improve racing performance (ie, cut time from a qtr mile run) ??????

you do for a moment stop accelerating while changing with the clutch ,, but doesnt dumping a redline pinged clutch on the upshift more than make up for it?
