How fast can Nightcrawler teleport?

Ive searched forever online and I cant seem to be able to find exactly what im looking for. Im trying to find of how quickly night crawler can teleport from point a to point b and how quickly he can "re teleport", like how long after a teleport does it take him to be able to do it again. Ive tried to factor him into some interesting battles, and this information would be helpful since I cant seem to find it, thanks guys!

His teleports are NEAR instantaneous. He basically just pops from one point to another in the time it takes for the "BAMF" sound to be produced. Kinda like the snapping of fingers.

And he can teleport repeatedly one right after the other in just split-seconds. Look at some of his first showings, when he's taking down numerous opponents at the same time.

Thank you, thats the information I was looking for!
