So far, I've been able to learn 33 buttons on the C7.

At first I only got about 20. Then I did a 981 reset, which I believe set it back to factory defaults. Then I took the "tap instead of hold for 2 blinks" advice, which made a big difference. This is when you're doing the learning process on the C7 and the manual says to hold the old remote's button until the C7 blinks - DON'T - Just tap the old remote button and the C7 will most likely still learn it.

But then I discovered while expermenting with the reset that the factory default operated my TV without any code input and I think I was actually able to pick up a couple of extra learned buttons by not programing in a tv code.

Now I suppose that could have resulted from doing quicker "taps" during my last learning process - I'm not sure. All I know is that my last try did give me at least 2 or 3 more learned buttons over the previous round (durning which I was also doing the quick tam method). Anyway, I think I'll leave well enough alone.

Hope this is useful to someone.
