You are absolutely right. Eveything here revolves - or should revlove around having fun - bottom line.
PB challenges are fun and thats why we do them.
However - they are normally reserved for true rivalries - thats how it has been in the past, and thats what I meant to convey in my last post.
If you want to run out a PB challenge every week because you enjoy it - than so be it. Have fun.
