Noob: hservo speed question

I just bought a new ABB with an Atom Pro. I’m experimenting with the hservo command. According to the atom pro manual the hservo command has a speed setting and the default is 255. I tried adjusting the speed of the servo to see how it performed. The servo seemed like it was moving very slowly, so I pulled the speed setting out of the code (relying on the preset) and the servo moved much faster. Below is the code. I would say when the program runs the code with the speed setting it is ~half the speed of the code that relies on the preset speed. I’m not certain that it matters, but I’m using HS-311 servos and a 6v alkaline battery pack.

enablehservo

srv0 con 0

hservo [srv0\0\255]
pause 2000
start:

hservo [srv0-11500\255]
pause 4000
hservo [srv0\11500\255]
pause 4000

hservo [srv0-11500]
pause 4000
hservo [srv0\11500]
pause 4000

goto start

Basically, I am looking for the range of speed values I can use with the hservo command.
