I'm not blaming MP for anything other than speeding the songs waaaaaay to much (also overplaying a lot in live shows, but that's a topic for another time ). The thing here is that people combine the fact that they use a click track now with MMs precision and technique, so call him robotic and all that.
Just like rumbo, I've never noticed the songs being played too fast with MP and I've listened to literally hundreds of bootlegs, aside from that single example of Disappear.
I think you can maybe point to a few more examples than that. For instance, MP pushed the tempo in The Glass Prison to the point that JP would regularly get tripped up on what were already nearly-impossible difficulty level parts. So it's not like it never happened at all. But that said,
(1) Even with that song, he made the judgment call that that pace served the energy of the song, and I think 99% of any given audience probably agreed and barely noticed/minded some minor slip-ups on some of the sweeps and guitar runs in light of the energy being given off.
(2) No matter how many minor examples we can come up with at the end of the day, it is still a relatively small number.
So, at the end of the day, it's a judgment call. And no matter what the call, you are going to have people saying "too fast" or "too slow." If some people feel MP was a bit too fast, it hardly ruined the songs. If some feel the click makes the songs too slow, it hardly ruins the songs. It is what it is.
