I forgot to add the tolearace reply to my previous post about pricing.

Here at AIT, we typically quote a value +/- 10%. 

This gives the fab guys some room to work and keeps scrap rates down.

However, the tolerance would be a function of a given fab
house's abilities since the material could be tested and
then the resistor size compensated prior to imaging/etching it.
