Given a discrete list of tactics and enough data, it's of course possible to generate a best strategy for any particular situation numerically. So yes, if your question is "should I pull block or chip block here?" and you are willing to throw out all the information specific to the situation not found in the data (e.g. the fact that the left tackle's ankle is a bit sore today), then you can do it.
But the point is that detailed blocking foot work is not adequately captured by such a framework (unless you're going to do detailed numerical simulations of every part of everyone's body). There is no concise way to explain exactly why chop blocks work well in certain situations, and why a hypothetical block which seems mechanically similar is completely useless in the same situation. Human bodies are complicated, and the answer is usually just "empirically, that's how it works out".
