In 4:18 we can see that the referee's counting is on 6 for both, because this is the first time he uses both hands to count with his fingers, and in 4:22 the counting is on 8 for both (as the referee's fingers indicate). The referee stopped Tyson on 8, I think it was more like a technical knockout (kind of "Well, I don't need to count to 10 to see that this guy is out")
That's not wayyy faster.

Its pretty much subjective, some people count slower others faster so yeah
