Cook timeline calculator
Set a serving time, choose the cut, and give yourself a realistic start window instead of a false single finish time

Find a realistic start window
Work backward from the serving time using a planning range for the cook and a proper rest window
Use the early end of the window
Finishing early with a safe holding plan is usually easier than chasing a late cook. Actual times vary with cooker behavior, weather, thickness, wrapping choices, tenderness, and rest conditions.
Choose a check point before the pressure starts
Set a moment during the cook to compare the actual pace with the plan, while there is still room to adapt. That is more useful than waiting for the target serving time to discover that the meat needs another hour or is already ready to hold.
