also.. wake turbulence is the worst if the heavier aircraft (bizjet) is
configured for landing, flaps and gear etc.. if he was still gear up.. and
in level flight... the bumps would not be so bad even if you had 500ft.

A quote from a popular primary text:
"The greatest vortex strength occurs under CLEAN configuration, high weight,
and slow speed." (emphasis mine)

(... and high air density) Their contention appears to be that flaps and
gear help break up the vortex pattern. The clean configuration at slow
speeds results in the highest AOA, supposedly the primary culprit.
