Hahaha, it's alright. I'm happy to answer questions. ^_^
At the lower temps I still cook them at 10-15 minutes. Like at the 210-215 range.
For the last long slow bake, it's just the 190-200 for 30 min.
I've never taken the box directions very seriously. I've never worried about thickness and all that either. I just judge it by size and think, well this is pretty big and thick I'll add an extra ten minutes to it. It's never been part of an exact equation. Most of the stuff you see in my gallery including this model are fairly thin and small and the 10-15 minutes works for them. I'm thinking the model would have to be pretty big for me to consider cooking it regularly that much longer [and I know I'll never attempt anything huge]
Hope that made sense and helps! If not, don't worry about asking me more questions.
