I'd use the snake method instead. Then you will achieve the desired low temperature for hours, without a steady rise into maybe a too high temperature too early.
If you're having problems with rising into the safe zone at then end, just use the stove in the kitchen. I'ts not cheating, I promise. Noone will ever know, and it does not change the final product in any way.
Overcooked bacon is not very nice.
For me, 2 chimneys unlit, and 10 lit sounds way too much, but on the other hand your vent settings might make it work.
