What GP describes is not T9. The thing known as T9 is a predictive algorithm based on a compressed dictionary that generates words from single presses on each key. If you triple-tap 2 with T9 you get "cab", not C.

I stand corrected on the name. My mom used what they described.

With normal pre t9, typing cab was a bit of a pain, 222222 if I remember the “end of character” code right. It was more accurate than typifying on an iPhone with predictive text though.
