This is a situation where giving only the total run expectancy is misleading. The bunt option may skew towards less overalls runs but at a higher occurrence rate where as the let them hit option may result in a bigger inning of more runs scored but lower occurrence. What I would want to know is.... odds of scoring 1 run, 2 runs, 3 runs, 4 runs, etc. with both options. The bunt option might be better for 2 runs or less and the let them hit option for 3 runs or more.
