Hmm - About 5 years ago I was able to perform a calculation based on a
little known statistical technique viz: If you have a sample of a
population n1 and and an independant sample of a population n2 and also
know the number of the population who are in both samples n3 you can
(with a simple formula published at the time in New Scientist magazine)
work out the number N which is the value of the total population. At
that time I was distributing Flagship and PBM Scroll (remember that?).
I thus had the information (Flagship subbers=n1,Scroll subbers=n2,and
both mag subbers=n3) and was able to come up with a value for N which
was approx 5000 the total UK PBM player population. I will not be
giving away secrets (because at that time Nick Palmer correctly stated
in Flagship that he had 1000 subbers) when I say that this gave
Flagship 20% of the active PBMers (not 15%). The figures have varied
slightly since then but we believe Flagship's percentage penetration of
the PBM market has remained resonably constant.

As a postscript to this story I would also add that after PBM Scroll
regrettably folded we received a letter from a player bewailing the
demise of PBM Scroll and saying 'I read my friend's copy every issue' -
It is not only GMs that despair of some customers!
