You're right. Sometimes comparing cams from differant makes is difficult for exactly that reason.
For duration, pay attention to the .050 number. That's really the only one that counts, as that is where airflow is generally considered to start and end.
As for power, way too many variables involved for a cam m aker to tell you that. Programs like Desktop Dyno are helpfull in comparing components.
