Hello @PPN and many thanks for that funny contest !
I never win anyway but enjoy playing with these "What have I got in my pocket?" games… "my precious !!"
So i think you must have a pockettable number of units...Non-realistic answer would be "It's over nine thousand!"…
But i'll go with 42 because it's the "Answer to the Ultimate Question of Life, the Universe, and Everything"
… Who knows
