No, you are less likely to score 1 run, you are more likely to score more than one run. Also, the chart only shows average numbers, so it really should never be applied to any one in game scenario because there are too many factors in play that are different from an "average" scenario. Also, the main reason not bunting leads to more runs is that you have one extra chance to hit a HR, but as a manager you should take into account your chances of hitting HRs. It is stupid to always assume someone will hit a HR for you when you need it, especially if it is Ecobar or Counsell or someone who rarely hits HRs. I would be willing to bet those charts would look much different if you threw out all innings without HRs.
