The two methods were compared in a variety of ways but in reference to top 5 vs top 5:
2001 Derby
BSF:
Millennium Wind...114 (finished 11th)
Balto Star...112 (finished 14th)
Keats...110 (finished 16th)
Point Given...110 (finished 5th)
Congaree...108 (finished 3rd)
PF's:
Congaree...-76 (finished 3rd)
Thunder Blitz...-76 (finished 4th)
Monarchos...-70 (winner)
Balto Star...-69 (finished 14th)
Millennium Wind (finished 11th)
Again, this was a one year study and Dr Roman summarized results thusly, "No general conclusions about the value of BSFs or PFs should be drawn from these singular results. BSFs have stood the test of time. They are certainly a profound improvement over raw time as a measure of performance. Nevertheless, the results do suggest that other approaches may be at least as accurate and equally useful."

Yes this is what I was looking for. I was looking at it just a few minutes ago.

He picked a good year for the comparison.
