That amount of slip is usually in the ball park to start. When I set the TA03 that tight, the diff action was also much tighter than I'd usually see. Since you seem to have to take half the car apart to adjust this thing once it's in there, I'd like to get it right the first time....
Any advice on setting it up? TIA
Bear in mind also that there is only one way of building the TA03 diff - and that is with the bolt fully tightened - the spring washers are what generates the tension so follow their orientation exactly. If you try and overtighten the bolt, all you will do is strip the thread in the outdrive. The TA03 diff does feel a lot tighter than a typical RC ball diff (because of the design), but it works well in the front of a Mini.
