Agreed. It’s not a stupid question (genuine ones rarely are) but as the old saying goes: ‘perfection is the enemy of good enough’. There are plenty of rabbit holes like this in aviation where it is possible to completely overthink a problem (or even to think there is a problem in the first place).
What are you trying to prevent and how is it defined? What difference would it make if you did it either way? If it isn’t an SOP there is likely a reason for that.
Fixating on trivia can have a negative effect in the real world. At the end of the day, there are tolerances and margins in everything and the difference in elevation between various bits of a runway is lost in the noise when it comes to practical aviation (unless you’re in Alpe d’Huez or Ulanbataar). Having spent tens of thousands of hours in the air, my understanding of the idea is to make it as simple as possible, and to avoid useless layers of complication and personal quirks that confuse anyone you fly with. Spending your limited cognitive resources on things that have no measurable impact on the operation means you have less to cover the important stuff, like which way to turn if you lose an engine...
