I'm saying this as a result of discrepancies in Quantum Torpedo technology. Only in one case we saw in which Q-Torps seem to be ineffective (in "Valiant" to which I maintain was an error), while in two others, they seem to be rather damaging.....
That's one possibility, the other is HOW the torpedo explodes. And these so-called limitations does not exclude Photon Torpedoes though. In WoTW, we saw a Photon Torpedo plow a large hole in a Klingon Cruiser, while in others (in the case of TNG's Yesterday's Enterprise), 5 direct torpedo hits only did moderate damage to a Klingon Bird of prey. Perhaps this was the same in the case of "Valiant".

The following makes me wonder, "Perhaps the angle of collision theory works for phasers as well?"

Quantum torpedoes are also less powerful than pulse phasers. In a Final Chapter episode two quantum torpedoes do a lot more damage than a half dozen pulse haser blasts. Quite strange.
