Yes - but -one addition - increasing the rotation never really slows the surface movement - the "WHY" is because under load, the load controls the speed of movement -
Buying superfast servos-vs super torque is usually a mistake -
on most modern servos, there is little effective speed difference and a lot of actual torque difference .
testing for speed with no load is folly.
In order to get fast servo movement -under load - lots of current is required.
There is no free lunch as power consumed is directly related to work performed.
The point many miss is that by using a modern digital servo of only moderate power -then using max rotation per surface angle, the power spikes (baaad) can be greatly reduced and make for a better system.
