Reality check, resolution with this encoder/pitch combo?

I have some of the Reliance servo motors I bought on ebay that have been
discussed here before. I've forgotten the exact encoder count but
working on the assumption it's 1024 lines I get 4096 counts.
If I couple this with a 10mm (.394) pitch lead screw 1:1, my spreadsheet
shows a theoretical resolution of .000096/encoder count.
Does this look right?
Application is a bolt on CNC attachment for my lathe, travels limited
and I'm not concerned with high rapids. Just want some good resolution
on the X axis.

Thanks,

Jon
