A thought for random consumption to keep everything stable: Charlie might not have dived straight into the CGM, but checked things out beforehand and perhaps tried an experiment of his own, adding some items to try to influence the process (his dog-tags, flight wings, etc, all already dipped in handwavium)... the effects produce a Puma-type and study of him and the process allows some improvements that eventually result in the Puma Machine?

--
Of all the tyrannies, a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end, for they do so with the approval of their own conscience.
-- C.S. Lewis
