Carbon Monoxide tent method - enter with the charcoal vs let CO build up before entering tent?

Leaving tonight

I'm currently eating my (hopefully) last meal -pasta followed by a vegan ice cream sundae- at a jazz bar above a little independent cinema near the location I picked. Today I will start my BBQ probably around 11 o'clock UK time and hope to be dead by the early hours. Within a couple of days my...

Zanexx is the only confirmed successful charcoal+tent case i've read here. They entered the tent with the charcoal and waited for the CO to gradually build up. A lot of people recommend leaving the charcoal in the tent for 30 mins first and then entering the tent and passing out quickly.

I'm planning to copy Zanexx and enter with the charcoal. I think it may give a better chance of success. It replicates how accidental CO deaths occur, where people die in their sleep due to a CO leak.

It obviously sounds nicer to let the CO build up to a high level, get in the tent and pass out after a few breaths. But, i think perhaps passing out quickly and going into shallow breathing maybe is less effective. Staying awake and breathing more deeply for longer, as the CO gradually accumulates, is a better option?

My anxiety about entering with the charcoal is that i have congenital heart disease and restrictive lung disease due to marfan syndrome. Zanexx's last message mentioned being short of breath, and i'm worried i could go into respiratory arrest and still be concious. I know the end result would be the same, but i just would much prefer to lose conciousness first. Getting into the tent with high CO levels, seems to ensure losing conciousness quickly.

Any opinions on this are appreciated.

CO is also my method, maybe in a tent or small room. I thought about exactly the same thing - let CO build up first, or go inside the tent/room together with the charcoal. I would say it's better to go inside together with the charcoal bc then there's still enough time to close and seal the zipper. I'd be concerned that CO levels will drop too much if I open the tent after 30 minutes to crawl inside.

In such a small environment like a tent, the concentration is going to build up so fast that it isn't going to make much difference.
