Even when the info doesn't change your play knowing your decision has much smaller error rate has great value. Increases in PE have value that allows you to bet more at the same RoR or bet the same at a lower RoR. Look to SCORE improvement to quantify the value. That keeps BR and RoR constant while calculating the optimal ramp for each in the comparison. The entire gain is in SCORE rather than spread across EV and RoR.Of course N0 is inversely proportional to SCORE but if RoR and BR aren't held constant to generate the 2 optimal spreads in the comparison N0 will not tell the entire story. Increase in PE from .51 to .67 has about a 15 to 20% increase in SCORE. Going to a PE in the .9's will give significantly more.
