Yes!I read a "zero to 0.0008" spec as "just don't angle it away from the operator and if anything favor toward you slightly." No?
I think the purpose of those specs are for allowing a longer time of usage before being out of limits again, i.e., the job lasts longer, and is more practically accurate in the real world where there is more than a DTI point pushing against things. Doing 'perfect' work when reconditioning a lathe will give you a nice, warm, fuzzy feeling, but with first usage accuracy will be deteriorating. Think of the specified tolerances allowing "final lapping to perfection while in service..."
