usually, when i observe the leonids, or the persieds, or any other
shower, masimim LM is ususally ranging from 6.0 - 6.3 i and my
friends at JAS could not go higher than that except once , where
we reached as i remember 6.4 or 6.5, and we were amazed of that.

i will try to goi out once or twice, just to estimate max. LM by
counting as possible the IMO triangles., by this only, we can get
"newrly true" max. LM.

it worth trying anyway.
