I don't know whether a basis or explanation is needed or not but the results looks impressive (I have not bothered to verify them myself, am sure they are true else someone or the other would have pointed it out already).
As for using the calls, I can bet some have already jumped into these. And why not ? Isnt that what many do anyways, "follow based on past performance".
Wonderful list man, keep it up.
Cheers.
