SP25 scanning speed

SP25 scanning speed

I came across this video the other day and was amazed how fast the machine was scanning. https://www.youtube.com/watch?v=kKKWpmvRg2s
I don't know if it's bad practice to scan this fast, but I was going to try some experiments to see how the speed would affect the measurements, Even with my scan speed set to 10 (15 is max on my LK machine), it appeared nowhere near this fast, in fact, I couldn't see much difference past .5. Is there another setting somewhere, perhaps in the LK config files that would limit this?
