Does this ever happen? I can't think of a single time when a heal target fell, and the medic immediately threw needles back. They just run for a new heal target. I can think of times where I've stabbed a medic, then fired my six into him, leading to me dying as I'm running away and trying to reload because he yelled OKTOBARFÆST! and held the button down while chasing me.

If there are no other healing targets around, most medics will either start shooting needles or suicide trying to ubersaw. If you're anywhere close to the front lines, you've just baited that medic into a deathtrap, alone. Killing the medic and his chance of ubering (imo) is worth much more than you still being alive. I'd count that as a victory. Like you said, even a noob medic is worth a player and a half.

Maybe in the old days. Usualy I'm ±10, and usually it's 0~-10 behind a heavy. Disregarding last night, it's been weeks since I got a +20 first-place or even an ultra kill, which was an every-round thing when knife worked.

They don't. If the engineer is playing wrench-monkey, by the time I see the sapper stick, he's already delivered a whack to it. By the time I see it break, he's already killed me with a crit. And after that, you hear me say on voice that I've sapped it and then you die instantly to an angry Level 3.

Here's something interesting I saw today - someone had a bind that said something to the effect of "I'm sapping a sentry!" in addition to using voice chat. Anyway, the sapper can be off by the time a nearby pyro is at the sentry or a demo has the time to lay a sticky or two. As long as they can do this much, they have a shot of taking it out. I still think that if you can convince your team to rush, or if they can see you sap something, you should do it.

I'd guess I have about a 40% success rate. Click here to see why.

Weird. Not only have I never seen that before, I don't think I've ever heard anyone complain about it. Does it happen often?

And if I could stab them in the back then I would but that doesn't exactly work when you must wait three or four seconds to move your arm after decloaking,

Valve wants you to actually fool the other team with a disguise for a little bit before you can rake in the kills. Don't you think it would be unfair if you could stab right from being invisible? You probably think 3 seconds is too long. I think 1-2 seconds would be too short.

Seems like the other team actually started to learn from getting stabbed. Switch off spy for a life or two and then switch back. Most of the time, they won't be quite as paranoid after the switch.

Everyone misses. Blame lag, your opponent's refusal to stand still, and the engine, like the rest of us. :P
