Hello EMIT. You're extrapolating the previous comment (pertaining to unneeded calculations some pilots make in the hope of maximizing Flex...which is unnecessary).
Leaving that aside, to help illustrate the career danger you could put yourself in, with your line of thinking in post #881. Take a look at this. (words are taken from your post);
Board of Inquiry (BOI): "You say you made additional LPC calculations, not called for by SOP. Why was that?"
YOU: "I experiment as much as [I] like, not every experiment has to be double checked by the co-pilot."
BOI: Do you think you messing around with flap setting in LPC might possibly have been factor in why you didn't detect the FO [insert the unrelated departure mistake here]
YOU: "The notion that there is risk involved in viewing different flap settings is wrong."
BOI: "Who says that, Airbus? Where is it written in the FCOM?"
YOU: "Well, no. It's not written anywhere in Company docs. But that's what I think"
BOI: "I see. That's all"
YOU: "Thanks, Bye."
BOI: "By the way, we've been firing people for lesser mistakes than the one you made on departure. Please wait outside."
Starting to see the picture?
