Eastie, I did look this up, and there was a section in the book. There is no simple answer as they cite 10+ variables that affect the combustion dynamics during knocking. However, torque loss clearly seems to be a function of spark advance and engine speed. The loss that results from retarding the spark advance can vary from 10% at low rpms to 1% as the engine reaches the higher rpms. This is a pretty general statement though, and does not necessarily directly address the 95/98 scenario.
