Efb E/o Accel Ht

Hi All,
Could anyone explain why the Engine Out Acceleration Height as calculated by an EFB (in my case 773ER), changes with environmental conditions? I have been playing around with it and found that it can change by 150ft or more depending on wind, OAT, QNH etc.
For example, sticking in a 40kt HWC while all other factors remain the same will make such a difference.
Additionally TOW and TODA changes have similar effects.
Shouldn't it be a fixed height AGL?
Thanks in advance.
