Bullshit with that incorrect flaps setting.

Bullshit with that incorrect flaps setting, let alone
tell the pilots that the flaps setting is wrong.

It would make much more sense to compare the
actual settings with that has been entered at the
preflight config calculations and tell the pilots
that they have not set what was required with
flaps and boost etc before they actually applied
takeoff power and not allow takeoff power to be
applied before those were set correctly.

See above

It would be stupid to try to measure that while taking off
instead of doing that before takeoff power is applied

Yes, there is also a different problem with the engines
not being able to deliver the power they were assumed
to be able to deliver the power they were supposed to
be able to deliver in the preflight calculations, but that
was not the case in the incident being discussed and
it would be much easier to discover than much earlier
in the takeoff run than V1 or VR
