I have no idea how much it matters, but assume the same temp target with a cooker full of butts: I'm pretty convinced you'll get different cooking times depending on where your probe is, ie. middle top grate vs. hanging in dome vent. How much? No clue, and I'm sure it depends on several factors, like the weather and how cold the meat started off at.
Anyway, I guess the better queastion is why Steve Petrone said his butts were getting done in 12-14 cooking at 250-275, while another self proclaimed wsm expert says his eight pound butts are always done in nine hours if cooking at 275, with no foiling. My best guess is that maybe the former cooks with both grates full and the latter only cooks one or two on the top, perhaps with the probe centrally located on the grate next to cold meat. I have no clue.
And you won't, really, even if those questions are answered.
I don't recall Steve doing large cooks. Maybe. Doesn't matter. 'Accuracy' of temp at grate level in a packed cooker would be, in a word, suspect.
Focusing on another's cooktemp
might help but quite possibly won't. Too many variables at play. Better to focus on the relative difference of, say, the way Steve was doing it before and what he then did, and relate that to what you've been doing and what you'd like to do. Then just go for it, keeping an eye on things and making adjustments if needed as you go. Even if you nail every perceived variable of someone else's cook exactly, there are many vague and unperceived variables that can result in a different outcome - or maybe not.
As examples: The last full cooker, higher heat butt cook I did I was at at least 300 lid. No bark issues but I rotated top to bottom. I do spares much higher, rotating if it looks necessary, with no bark issues. Why the difference between your experiences and mine? Dunno. I know my therm is accurate and I am sure you know yours is. There are other variables at play.
Cooking outside is not like cooking inside in an oven. Though this is obvious, more than a few outdoor cooks get frustrated when they try to do the same as someone else but the cook comes out differently, taking longer or shorter, or with some other sort of difference to the result.
Differences between cooks of apparently closely similar variables - even differences within a cook - lead sometimes to frustration, and lead many to believe there is such a thing as 'stubborn' butts and to repeat the
barbecue myth that 'every piece of meat is different'. Cooks - the individual people and the individual cooking sessions - can be quite different, despite similar appearances. </div></BLOCKQUOTE>
Your examples of "vague and unperceived variables" simply confirm to me the necessity of rotating meat if cooking at higher temps. See, I learned something, so thanks a bunch.
As for the yang to your yen, how many times have I heard that "bbq isn't rocket science", we're all cooking on the same cooker, and you've already established that the meat is standardized...so what's left for this forum to be an educational tool is for data to be recorded and reported. (Sorry if sound too serious.
)
Anyhow, are we gonna miss some stuff? Sure. Like I mentioned above, there's always gonna be unknown factors that come into play, or "vague and unpercieved variables", as you so aptly put it.... especially if folks are no better at logging data than I am.
Thanks for the insightful response, Kevin. Sounds like I need to do more cooking and spend less time here.
