Wow, you've put a lot of work into that post Mark, so thanks for going to the trouble & it's a thumbs Up from me. (:
They're some pretty interesting stats imo ... and woo hoo I'm pretty happy with my 37.65%, which I would take any year!
So, my New Years resolution is to better that 37.65% now ... when did you say that 1st tipping comp for 2011 kicks off??? ... hehehe!
Happy New Year Mark (and to all the tipsters)!
