What about when the old fogey from the CAA decides you now need a call at FL200 and FL300? For what? Anyone worth their salt has actioned some drills at FL100 wether their company SOP calls for it or not.
Superfluous SOPs only detract from the whole ethos. If one item is deemed to be questionable, then all items become suspect by default.
Just because eons ago some old fart used to have to retard the throttles on their Viper engines in the climb and used FL200 and 300 as a reminder does not mean modern equipment needs to be governed by rules that are irrelevant.
To my friends who are old farts, I wish I'd flown in your era when pilots were better skilled and very much more respected.
