Looks like you are doing something right to be riding in A group.
I noticed that everyone has their own form, what works for one may not work for another. That said, I think everyone should try the recommended "form" and let it morph as you get more comfortable.

Like someone mentioned, get your head out from behind the windscreen.
Try to get your upper body off a bit more, so basically the same as above....if your head goes, your body will follow.
Outside armpit on the gas cap. Drop your inside elbow.
Don't worry about looking like a frog. haha I think I look pretty funny too from side or rear shots.
Concentrate and consciously try to change your position if you are searching for your perfect "form". Sometimes to do this, you need to slow it down. It's hard to concentrate on something new when you are out there trying to go "fast".

I seriously believe the "perfect" form is different for everyone.
So the above are just things that worked for me. Then again, I'm far from fast.
