I believe your calculations are shown by your experience. The 20 "actions" you calculated theoretically transfers to the actual 18 you got, 9 ins and 9 outs, if I'm understanding you correctly.
In an education culture that hinges on having the perfect grades and perfect SAT scores to get into the perfect colleges, I enjoy providing an environment where students are encouraged to test their own hypothesis, challenge their assumptions, and regularly fail. - Michael Corsetto [more]
