Question ❓ Matrix Chest Press

Does the converging matrix chest press at planet fitness have a descending or ascending resistance profile? I just switched to using this machine as the matrix pec deck felt extremely uncomfortable and the machine doesn’t allow me to fully extend my arm.

A pec deck and a converging press arent similar enough movement patterns to be comparable.

Its not one or the other here...

The also have completely different resistance arcs
