What possible criteria could you use to say one "beat" the other? Apples and oranges. Positional RS is NOT a pace rating. That' like asking what time is it and getting a reply "Dark."
Clearly, Brohamer does not bet by running style, but uses it as part of his pace analysis. If you did not do it that way he describes the process, you cannot compare it to anything.
BTW, we call those horses you describe "early pressures." Barbaro and BB were not need to lead horses.
