Try reading the statement again, here it is:

To summarise your missed point, the pilot control inputs cost energy
that is not factored into simple glide/time analysis.

This is absolutely correct. But then, I dont understand the connection
to your first statement regarding the wind. Additioinal drag by control
input is completely unrelated to the presence or non-presence of wind.

Itls a turn upwind to downwind. That involves 2 direction changes, one
to reverse course and the the other to line up the runway. If there's
wind there will be an effect on line up. Try thinking about more
factors that cost altitude OK?

A crosswind should only help you line up. If you stay aligned with the
runway and turn into the wind then it will reduce the offset after you
complete the turn. If you allow yourself to drift with the wind then this
will further work in your favor. If you turn into the wind and push upwind
during the takeoff then the wind can make things quite exciting, but don't
do that.
