Delving deeper into Markov, and I see that the answer to the question to 'who uses Markov?' below is that oasis already uses Markov Chains to determine Stocks to pick.
Markov looks at individual states and presents percentage probabilities of outcomes. If we think of oasis indicators as states then the reporting system is producing the Markov products from the probability Chains.
Markov nicely formalized the generalized situations and gives a way to visualize what is going on.
The Markov Chain that oasis is trying to formalize is pretty specific and quite complex, by looking at the state of indicators in the current period and comparing to a desired outcome with maximal probability.
At least what I am trying to do has a name
