Checking ribs a few hours ahead won't get you anywhere. Ribs only take a few to several hours to cook in the first place, depending on cooktemps. A probe inserted between the bones will go in with a lot of effort when the ribs are not cooked enough, then progressively less effort as they become tender, till the probe goes in without any effort - like going into soft butter. They will be tender and juicy at this point, but not fall-off-the-bone.
It is easy to avoid FOTB ribs: Don't cook by time. Simply cook till the ribs are tender while still in the foil. (Very easy to remove a foiled rack, recover the grill, open the foil, check for tenderness; recrimp the foil and return if not tender; remove if done.) Return the ribs to the cooker for several minutes, unfoiled, to firm the bark. You can sauce at this point if you prefer. Me, I cannot abide ribs sauced while still on the cooker. (An extremely thin veneer of glaze can be nice.) But if you prefer the sauced thing go ahead. The ribs should not overcook in the time it takes the sauce to set (and this can be shortened by first reducing the sauce some before application).
Never been a fan of tearing ribs. Imo, learning what tender meat feels like with a probe gets you farther. All fattier, tough meats cooked to tender feel the same when undercooked and the same when done/tender, whether pork or beef ribs, butt or lamb shoulder, brisket or chuck.
Yes, variables can be different, often are, even if it seems like everything you're doing (and even the meat you are cooking) is the same as before.
I don't always foil ribs but the cooks are a bit more consistent when I do, timewise. I foil to add a flavor layer, primarily, and it works well. When I used to cook ribs lower/slower I did the same thing as I do at higher temps: cook the ribs till nicely and richly colored, foil with a juice or juice/stock reduction, cook till tender in the foil. All done by look and feel. No clock needed - and better without.
