Number of HX, Profit, Earnings Ratio and Risk, page-23

firstly i do love the quote from Oscar Wilde which your name reminded me.

" never regret thy fall o Icarus "

right now there is many different ways Things can be built. and into the future that diversity will remain.

one build to rule them all.
one build to find them.
one build to bring them all.
and outdoors bind them.

seriously though finding the market saturation point early will be the key here, my guess and only a guess is somewhere between 1500 and 10000 units.

big window i know but competition etc etc etc still to early to throw accurate darts
