Pilots with experience do not spend much time with the FMC doing that sort of thing. Had a copilot on a 757 put in the whole MEX engine out emergency procedure on the FMC for every takeoff. Finally told him if we followed it we would cut all the corners of the figure 8 pattern and be illegal so why are you doing it? Too much work and just more confusion, especially with all that route 2 garbage. Check Airmen are the worst.
