Yeah thats why he was about to get shot down by a Gatling gun I've seen the shows and I hate to tell you this but you are still over exaggerating a bit. He's fast but let's not forget that when Bruse Lee fought he could make his punches seem like a blur because they moved so fast but he wasn't really going 100 mphs was he. Kenshin when going against people he should be way above in speed really doesn't do that good. Point He can't dodge when he gets hit by an apple all the time. He is a normal human also and therefore unable to go at those speeds.
They show case he is human all the time when he gets hit and such. He is fast possibly faster than the fastest man ever but that puts him at 25 to 35 mph tops.
With Terry like I said a person with only a small amount of the prginal Bane's Venom input was shown as overpowering Terry in the suit. That would put the guy at around let's say 800 pounds lifting maybe 1200. Thats the point it enhances but not that much.
