I observe the same in my setup Troy, although it is very minimal so I average between the two.
The template that they send out is for a 250mm mirror not 254mm mirror (strange) so i spent about 15 minutes moving it around with 2 sets of eyes judging.
As for a star test I think unless you have a solid set of spider vanes, its going to be hard to make fine adjustments to the secondary without sending it up the duff.
