i need to know

Yup. They don't provide /that/ much of an advantage over normal weaponry, and certainly none that would impact a speedrun.

counterpoint: rpgs open deposit boxes in a way saws cant

@rms the difference in time is about a second and i don't think that impacts any of the runs we have currently on the leaderboard - nightmare ro-bank is certainly saw-based

But some runs use the rpg, like the runs on diamond store, and those ones rely on the blast radius of the rpg, and I'm not even sure you could do the same strategy with non explosive weapons, because it would take time to shoot, and even half a second could affect the strategy working or not.
