Hu,
I have also been using the JOB SHEET info. I have been attaching a copy of it to my digital photos of the actual setup, in the setup files. I also have used this info for bidding also. When a customer sends in a model to bid on I go thru and set the job up and run the post and tool manager and then look at the time figures to get my bid. So far It has been a safe bet. You need to make sure that your speed and feeds are right, but you would with any bid setup.
