Oh, you just dealt with "Buchholz hydra expressed by matrices" but not with an algorithm which works in the same way as known PSS, right...?

Pulling back the expansion rule trivially gives a terminating strategy, but it has nothing to do with PSS.

Obvious, because you are not trying to prove the termination of PSS.

For example, I can call any system presented by matrices with trivial expansion rule "PSS". Then I can verify the termination in one page. Are you going to do such a trivial work?
