I declare Canadian whiskey and Seven up as oxygen for the brain but tomorrow it may smolder a bit.
I really think you generalized this. Limiting or controlling the oxidizing agent(oxygen as it was referred to) is only part of the equation. The density of the fuel(charcoal) is another part of the equation. You can burn at the same temp but it would last for a different rate, vice versa. Simple BBQ math would also assume that too much oxygen without adequate room for the carbon monoxide to exit would cause the smoldering to cease. Like i said, i think you generalized and left quite a few steps out, as i have too generalized.
