(meteorobs) Moon's deflection of Leonids

apparent position on Friday night/Saturday morning being so close to
the radiant, I wonder if the net deflective effect of the Moon's
gravity had an appreciable net positive or negative effect on how many
meteors hit the Earth.
I had done a simple hyperbolic passage calculation to address this question
just prior to the Leonid shower. The results were for a radiant shift of
more than a tenth of a degree the stream portion seen by an observer must
have passed within 1100 km of the moon's surface.This amounted to the Leonid
radiant situated no further away than the radius of the moon... a geometry
not encountered during the 2000 Leonids. Close but not close enough to
cause any significant deflection.
