I also concur grouping is a good way to approach the situation. Maybe enen selecting a common variable would work.
As for the question about the (6) in the formula; it,s easier for me to think in terms of product tolerance as noted in the first sentence of linearity on pg 35.
The 6 being the nominal reference value,as determined by layout, and the 2 and 10 being the upper and lower tolerance limit. Now these limits can be either product tolerance or actual results produced by the process.
