um...really? So the day he steals the base that puts him over the break even point, there's no longer any risk associated with future SB attempts and he should run at every opportunity? Is that really what you're saying or am I misunderstanding? Um... yes. really. If the runner has amassed a SB% that exceeds the breakeven point by running at every single opportunity, then you continue to run him at every single opportunity. Or, if you prefer real life situations instead of impossible hypotheticals.... then if the runner has amassed a SB% that exceeds the breakeven point by running only in certain situations, then you continue to run him in those same certain situations. This goes to the definition of what a "breakeven point" is. There will be times when the runner is thrown out, and runs are not scored that might have otherwise. They will be outweighed by the times that the runner is successful and runs will be scored that otherwise would not be realized. If the percentage exceeds the breakeven point, then there is no risk. Math isn't that hard. Don't try to make so. Yikes. ok. In order to determine whether a runner has hit the 75% point, do we use career stats? Just ML career? the last season? truffle gets to decide.
