Her temps, she's (or assistant) is pushing things open just a bit..or more, periodontal ligament movement? I had one account, who I routinely had to scrape the last molar contacts by about 1/2 mm just to make sure he had contacts. It was a real nightmare, until his assistant left, and when the new one came on board, now no problems at all.
What I would do for that Dr, and I routinely do, is to keep aside a designated BP with a new blade in it, then on a solid cast, I lightly scrape each contact 3 times. I know it may seem inconsistent as far as day to day hand pressure scraping, but as long as you use the same BP and change the blade out once in awhile, this could help. I mark the bottom of the cast with a Sharpie of how many times I scraped it, just so we both know in case it's to much. Try that as a starting point with her, and go from there as far as your scanner settings or when your hand building units in confirming your contacts.
