not for me it ain't... I wait till I have my best BARK before paper goes on... then the purpose of wrapping is to trap it's juices the last few hours....The purpose of wrapping is to beat the stall, by sealing the meat in paper or foil after you've reached 160ish IT you retain moisture that steams within the wrap powering you through the stall.
If you're unsure of grill temp you can always wrap and move it to the oven.
So as you see, just like Dr. Fauci, there is no real true science, it's just personal preference
