hover: how tight is tight?

Do you believe there is variation of result for the collision avoidance alignment asst2?

How would you know result variation is actually possible?

In other words is the success the same identical alignment were it done by another person on another asst2 pc?

Or, the successful alignment is NOT identically recorded irregardless of whoever performed it and irregardless of the asst2 pc system utilized?

I ask this because previous mavic air froze absolutely still in underground bunker after successfully performing asst2 collision avoidance alignment (three: fwd, rev, dwn). But grapevine replacement factory new “inches” and recorrects
