I can't recall there being any values for stability in the AMM for this. I vaguely recall we had engine run documentation which provided this. Sorry, I've been out of the industry for a while.
However, the AMM did say that there should be sufficient fuel in the tanks by the end of the run to still cover the hydraulic fluid heat exchangers (900kg in outboard mains, 2450kg in inboard mains)
