Hey Alex, if I remember correctly the 'tracking speed' you are referring to to are the correction rates that would be applied if you were running an autoguider scope. It more or less specifies the step size that any correction would make. The more accurate your alignment is the smaller and better the step needs to be but if your alignment is well off then the correction step may be insufficient to maintain the target in FOV and bigger steps may introduce some degree of image movement and poor resolution.
The Holy Grail would be to have a perfect alignment and perfect sidereal rate and not need any corrections from a guide scope but .... I think I just saw pig fly past ...

Basically unless you are running a guide scope system it has no relevance to your normal operation at sidereal rate for stars etc.
(The other rates will be for Solar and Lunar Tracking to allow for their differing rates of travel and some PEC rates IIRC )
