Malish, I don't now who "us" refers to above. As for me--I hope you'll continue your test program exactly as you see fit. Congratulations on your continued progress.
“Us” refers to members who are grown adults and don’t try to turn everything into petty bickering. A group you are not a member of.
Testing different cruise settings is a normal part of testing and included in every Pilot Operating Handbook.
You would know that if you bothered to learn basic pilot skills instead of wasting your time making petty comments and trying to constantly start arguments in every thread.
