Acceleration altitude and engine-out acceleration altitude

Hi!

Let's assume that we are establishing NADP 2 as 1000/1000 AAL and aerodrome elevation is 200ft. So we enter 1200/1200ft on the PERF TO page as THR RED / ACC altitude and we leave the EO ACC which is on the right side 1500ft as default.

Let's think that we've checked the RTOW chart and realised that Min Acc Alt is 1700ft so we updated the EO ACC as 1700ft.

For example lets say that we had a CONF 2 takeoff. And after 1200 ft with the first flap retraction we pulled the THR LVR to CLB detent and started acceleration to full retraction of flaps and at that time we had engine failure and we were still below 1700ft

Shall we also update -1200/1200- as 1700/1700 or 1200/1700 in order to guarantee the 2nd segment obstacle clearance if we encounter engine failure during second segment?

Thanks for your interest
