So I've been curious about this. I know it can be done, but can it be done safely and is it that much quicker? I've still got my stock clutch and it's got plenty of life left in it.

Obviously this is for track racing (drag) purposes and not for daily use.

In your definition, what is power shifting? There are a few different definitions people use, but I want to know what yours is before answering this question.

Does your TWM have a ton of play in each gear?

Keeping your foot on the gas as you push in the clutch and upshift. I'm not interested in clutchless shifting if that's what you thought I meant.
Umm, there really isn't anything wrong with that if you can shift fast enough, the key is that you don't want to go up more than like 300rpms or so. LNF's came from the factory with the NLTS (No Lift to Shift) option, which is just that, and you had .3 seconds to get to the next gear (if that tells you how fast you have to shift). By doing that you really don't increase the RPMS's to the point where it is hard on any of the driveline. So yes, you can do it, and yes it can help. NLTS'ing on the SS/TC's will shave about .5 - .75 seconds or so off your time in the 1/4 mile (depending on boost and setup and whatnot), however, it's not as impressive in the NA's or SC's. They only shave about .1-.3 off. Nothing too impressive or nothing you can really feel a difference in.

I see, well any bit helps as long as it doesn't threaten my safety and the drivetrain. I'm very confident I can shift into even number gears (1→2, 3→4) within the time limit, but the odd gears might need work as the throws are more complex and longer.

Does your TWM have a ton of play in each gear?
No, I'm not quite sure what you mean. The shifts are short and accurate, almost notchy I'd say, and you defiantly have to go around 'the wall' when shifting into odd numbered gears because it'll block you if you don't throw far enough. I used to have big trouble engaging 1st at stops, especially when cold, but that was remedied somewhat by new tranny fluid (Dexron VI). Car never popped out of gear either.

I drove my buddy's 2001 S4 and it's like the linkage is made out of rubber bands.

No mine is the same as described but when you're in a gear it seems like you can move it around far too much and it should be a tighter fit where the ball goes. I'm running Royal Purple Max ATF in mine and it's been better this winter.

Hmm, I can't recall off hand, I'd have to check that the next time I drive. I don't usually play with a gear once it's selected, but I have a habit of fiddling in neutral (side to side motions) at red lights and quickly going through each gear and reverse in an attempt to loosen it up from cold tranny fluid. It's OCD more than anything else.

I can pop it into neutral without disengaging the clutch, but I never made a habit of it.

I do the same neutral thing and it annoys me because there is a spot where there is really low force then as the sifter picks up force it feels better, as in no unwanted movement.

I can't say I feel that 'unwanted force' you do, except when trying to engage 1st at a dead stop. What I do is as I'm slowing to a stop, I push in the clutch and try to engage 1st. The tranny will lock me out until I fall below a certain speed. Still keeping pressure on the shifter, it'll fall right in with no fuss below 5 mph. The only 'minor' issue is that since the car is in gear, you'll have to hold down the clutch for the whole time that you're stopped.

I was going to try a little power shifting today on the bridge to Laval, but it snowed over night and the roads are a bit dicey.

Scratch that. Ton of play, about a half inch each way per gear.

Okay so the same as mine then, it has always annoyed me and I've been tempted to get the BPS because of it.
