Alright, riddle me this:
I haven't seen a lot of good data besides the marketing that Cervelo has put out. For instance;
At what depth is a rim considered to have an "aero" benefit? I see manufacturers with rims as shallow as 22-25mm touting their "aero" profile.
Where does "aero" out perform weight? Making a rim aero typically involves making it heavier, particularly if you're using alloys of any kind. Does an aero profile actually outperform a 100 gram gain to the rotational weight in a rim? I haven't seen any data that says "making a rim of 30mm aero profile is the equivalent of shaving x grams from the weight". Lennard Zinn, by the way, says that for almost every application save for solo breakaways, weight trumps aero everyday.
I guess my point is that I strongly suspect this is a bunch of marketing. It was getting harder to sell stuff simply on its lightweight merits (you can only do so much with a box section rim) so aero is the new "hook" to sell people more stuff for even more money...

As to most of the rest of your questions, the answer is it depends. What's the course like, the weather, how much power can you put out, ...
And finally, you have the right to your suspicions and opinions, but the facts don't bare them out.

I just can't "bare" the suspense...

I don't really want to argue aero tipping points because it's like arguing how long is a piece of string. It's as long as it needs to be and to gain any significant time on aero wheels you really need to be going fast and for long periods of time.
Congrats on the race but it wasn't your wheels that made you win, it was you. Unless you won by some small fraction of a second. If the wheels gave you confidence to do the break and push yourself for that last 1k then great I have no problems with it. Some people gain confidence from a lucky shirt/jersey, a number or some ritual. The mental perception is a huge deterministic in any competition (and in life). But it wasn't because of the aero properties of your wheels.

hehe, yes moot. I thought it looked funny when I typed it, I was tired but couldn't sleep.
