But we must consider another point too. We witness faint meteors in between the hundreds of stars in our field due to their movement. If a faint star appeared for about one second we would not realize it. We need some degree of movement when witnessing a meteor. On the other hand, very fast-moving meteors are easily missed too.
Medium velocity is optimal for perception.
If you are going to observe several showers at the same time, which is quite possible, you have to take care that their radiants do not lie in one line as seen from your field centre. Otherwise meteors from these radiants cannot be distinguished by their path directions, and distinguishing them by their angular velocity and path length alone will become difficult and more uncertain. If you are forced to change the field, note the time of this change and the new field. For analysis the time of such a change should be identical with the boundary of an observing interval. Observing a meteor When a meteor appears keep a cool head.
