And your point is?
My point is doing one case with Tempilaq isn't going to get you consistency across 100 cases unless you paint each one of your cases individually or are using a timing method of sorts (and I don't mean 1 Mississippi, 2 Mississippi). Even the DIY annealers have a controller that helps you time within fractions of a second the length of time your case is in the flame. Once set, all of your cases will receive same exposure to the flame and be, for the most part, annealed consistently as long as you monitor the flame length and keep it basically at the same temp.
