Just a side note to this discussion. There comes a time when the check airman's critique is just an opinion. With 30 years and about 20,000 hours I don't have to accept everything the check pilot says. We are both experts and by this time I know what's important and what's not. Some things are blatant mistakes and there's no way to get around it but there are several ways to skin a cat. His method may not be more valid than yours.
Stick by your guns if you're right. Just make sure you are right.
