3 months ago I would be telling you that the CG of an aircraft does not change. If the design was 60mm then that is what you use and then add or move weight so it balances at that measurement.
Now I am not so sure since my SS V2 flew for over a year at 60mm and now it is better at 70mm. While I haven't got a good reason I did make a number of modifications to the fuse. This could have made the CG change but it should not have.
I know that doesn't help you but I can only suggest you try balancing at a few different CG measurements and then perform a hand tossed glide to see if your plane performs properly.
