If I ... & Would it?

If I  have 3 pork shoulders all around the same size weight but only have 1 meat probe using a flameboss 100 on a large egg at 230 degrees using a swing grate for 1 of the shoulders so it would be higher in the dome....  Would it all be done to the same doneness at the same time??

I say butts are butts! and usually none of them cook the same, I did 3 yesterday and one was done just a little sooner than the other two. All 3 were 205 internal when I FTC them and after only a 40 minute rest in cooler one was much easer to pull than the other two. Now I'm not beating on my own drum but it was gone in no time at a good friends 50th birthday party. Butts are done when they are done.......... very easy cook and very forgiving too, they just don't care what temp you cook them at but they are done when they are done regardless of how long we think they should cook.

Each piece of meat is different regardless of weight. They may be done at the same time but probably not and may be off from each other by as much as 2 hrs if they are 8 lbrs.  I know this.  And the one higher is probably going to be done fastest if identical weight.  Probably, but certainly not "for sure".
I would put the probe in the smallest and the smallest in the bottom and start tracing tips for each piece when the probed one hit about 160 just to get the delta between them and plan for at least a 2 hr difference if going at about 250-275 dome.
