Am I in a minority of one who feels that these impromptu self-created extra checks just get in the way?
Maybe.
A few old timers (myself included) will complete a very brief aircraft configuration check just prior to entering the runway, for takeoff.
This configuration check is...
Flaps/slats set properly.
Spoilers down.
Stab trim in the takeoff range.
On the runway, and lined up, check compass headings for agreement.
These are known 'killer' items from past accidents, and therefore, in my considered opinion, deserve a second look.
NB.
This configuration check was a mandatory item where I first obtained jet aircraft training on the B707, long ago...PanAmerican.
