Time under tension and Partial movements?

[F4iGuy]

From what I've read hypertrophy occurs at 30-40 seconds time under tension.

We usually do sets of 8-10 full range repetitions to achieve this TUT.

It seems a lot of the pros (Jay, Ronnie, etc.) Stick to the 30-40 second time under tension rule but do it differently.
They incorporate more reps (15+) with partial movements (avoid top/bottom 3" of an exercise) and wind up around 30-40 seconds TUT.

Is one method more effective for hypertrophy? Should you incorporate both? Thoughts?

Full range is best IMO but once you reach that level of development it can be easy to get injured and lose your contract. They train in the manner that they do to avoid injury for the most part.
