With all due respect for the other contributions by all members (including mine), this is the single most important experiment/post that I have seen on the BS.
The deductions are multiple, but importantly it may just help us to adapt the height based on the style of pizza and other preference, without making any additional mod.
My oven was great out of the box (except for the misaligned axis), but was slightly more burning in the center than I desired. The deflector improved the results, but your new science just leads me to experiment with height (on a straightened axis).
Thank you. It takes tremendous passion and dedication to the cause to do that, although I understand that it must have been a lot of fun for you.
