13094... seems to be the smallest integer escaping gravity.

I had assumed that a plus and a minus were equiprobable but, empirically, I'm finding that a minus may actually be more probable than a plus, at least for small numbers. This helps keep things down. However, the long-term evolution of 13094 argues strongly that, on average n becomes a number greater than n, and the eventual downfalls in the evolution of 199, 10853, and 10886, are the exceptions, not the rule.
