I have had some do excellent, and some do so so. In the end, they all worked out. even if they were off a little bit, the cuts are at least straight. How do you mess up a cut on a panel saw. It's impossible to make a crooked cut, no? Too short or long i could see, but crooked? I find if I tell them upfront I need them really close and will look out for them if they take their time and help me out, they do a good job. I have even asked the help desk who makes the best cuts and they always call someone to help.
