Yearly Distance Record Attempt (Tommy Godwin - 75,065mi/120,000k)

Right, changes to https://goo.gl/RBHtiS made.

1. I've pulled the accumulated miles from the dates comparison sheet,
   as I'm not sure what it was adding really.
   
2. I've added rolling average distances both as a sheet (5, 7, and 14 days) and a chart (5 days only again)
   
3. I've added Steve's latest plan to the other plans, complete with all of the maths updated to look after itself again.
   
   

Enjoy, and if you post a link to it, please try to use the shortened goo.gl version, as it allows me to track how popular it is (anyone can see this data at https://goo.gl/#analytics/goo.gl/RBHtiS/all_time )
