Dear Jackie et al.: Stochastic refers in a decidedly technical way to chance, in the design of statistical and mathematic operations.

sto[chas[tic 7stb kas4tik, st!38
adj.
5< Gr stochastikos, proceeding by guesswork, lit., skillful in aiming < stochazesthai, to aim at < stochos, a target: for IE base see STING6
1 of, pertaining to, or arising from chance; involving probability; random
2 Math. designating a process in which a sequence of values is drawn from a corresponding sequence of jointly distributed random variables

I think it is a pretentious misuse of a technical word such as "stochastic" when it does nothing to facilitate the reader's understanding, and in fact is certain to baffle the reader. As if I referred to your "calcaneus" instead of saying "heel".
