Are most things covered during TR and/or airline 6 month checks?

Hey guys.

Recently completed TR on the 320, and though I understand a TR will not cover all failures, since there are so many, but will cover a lot of the important ones.
I'm wondering if we will be surprised with these failures in one of our 6 month checks? Or was my TR program not such a good one?

For example. Never got an engine dual failure, or landing with abnormal landing gear, VERY briefly did unreliable airspeed.

Thanks!
