Just a few calculations to mention:
Orch: I am putting your cross-trainer stats under the Gym heading.
Erica #1: You swam for 30 minutes on one occassion and I popped in a distance of 750 yards for you as this is your average distance in that time!
Erica #2: I have absolutely credited your horrendous hour of dragging luggage around - you poor thing! That really ought to have a catagory of it's own.
Kevin: you walked for about a mile and I popped a time of 45 minutes in for that - based on your figures for previous walk.
I am really putting these notes in for myself incase I need to look back at anything! It doesn't take much to confuse me
