imo it's easier if Daz does the inserting and formatting of the table (sorry daz). for the reason that the thread is readable and entry errors are less likely to happen. just a thought.

seems like a good idead to post my formula for excel from an earlier post.

this might be of use to any other geeks that keep a race record in excel.
=ROUND(1-(A1-B1)/(B1),2)*100

cell A1 is your time. cell B1 is the winning time. It works if you have converted to seconds already or if you format the cells to TIME
