I know what 'most' recommend. I see no reason to cook typical barbecue - especially commercial pork - at 225. (I cook most stuff much higher. Butts are the only things I low/slow. For me that's 250-275.)
Regardless, and regardless of the temps at which you choose to cook, nothing imo screws up new cooks more (and this can continue long after the cooks are no longer new) than a) feeling the need to temp the cooker in two places (grate and lid) and then, often, fretting about the difference, or fussing with grate probe placement and b) focusing on internal meat temp.
Whether meat cooks at 240 or 280 or 310 doesn't really matter. Whether one targets, say, 275 - but there are spikes to 325 or drops to 220 doesn't really matter. In ALL of these cases the ONLY thing affected is how long it will take the meat to cook to tender.
Getting your cooker going and shooting for some specific cooktemp target is fine. I used to say - out of deference to those that temp at the grate - that it didn't matter if you temped at grate or lid JUST PICK ONE PLACE. I don't necessarily think that it matters still - but I don't think that grate temping is actually terribly reliable. Too many variables at play - proximity of probe to meat, proximity of probe to grate edge, evenness of burn, whether water is used or not, whether ceramic is used or not, whether, if the probe is hung below the grate, moisture is dripping onto the probe. None of this matters when temping in a vent hole at the lid. It is simply, imo, the best place to check temp. (Whether the temp at the grate is more or less is UTTERLY immaterial.) It is, then, just a matter of working off that reading. I stick a therm in a vent hole. When I feel the need to monitor remotely - which is rare - I use my Mav and stick the probe in a vent hole. It's the most consistent place to check.
Neither knowing the lid temp (or grate temp) or the meat's internal temp or that this or that meat has cooked for this or that many hours will tell you whether the barbecue you're cooking is going to turn out spectacularly. Only focusing on the meat itself - how it looks, smells and feels - will tell you that. And it is this, imo, that needs to be the focus. Learn that - and this comes from doing - and you will cook all manner of barbecue at any possible temps in any possible cooker under any ambient conditions perfectly -
every time.
When something doesn't come out well it is not (as you might read here and elsewhere) that the cook had a 'stubborn butt', or 'bad ribs' - or any other such nonsense. If the meat didn't come out well the problem is the cook, not the meat - and the problem arises from not focusing on the main point - how the meat should look, smell and feel when it comes off the cooker.
This is pretty easy. Where it seems difficult - and how it is often unnecessarily complicated - is because of all this intervening stuff (temps and temp swings; spikes and drops; times per pound; internal temps, etc., etc. - that make it seem like good barbecue is all about focusing on this stuff and not about focusing on the results.
I'm not ranting here (really!
) Temp where you wish (you've heard my suggestion; the choice is yours) but do yourself a favor: Use whatever methods you wish that you know, read or have told to you. Try different things. But
always focus on the meat. It will tell you when it is tender. By doing this you'll get your food to where you want it to be sooner and with much less hassle and worrying.
