BAR
Whilst looking at the current standings in the clubs BAR competition I noticed that the qualifying speed is calculated as a mean of the average speed for each event.
Maybe this is the way BAR events have always been but it’s actually mathematically incorrect. Due to each of the events being a different distance using a mean of the average speeds gives each average speed an equal weighting ignoring the distance it was achieved over and may potentially skew the overall average speed.
In fact this does currently have an effect on the current rankings in the competition as of(23/07/2010), placing Richard in 1st place (24.73mph)and Chris in 2nd (24.69mph).
A mathematically correct way to calculate the overall average speed is to sum all the times and sum all the distances then work out the average. This actually gives Chris an average of 24.36mph and Richard 24.24mph reversing the positions. I haven't checked further down the rankings for any other changes.
The Stig....
Yes, you're dead right. But... it's always been that way ever since the BAR was first dreamed up however many years ago. It's always favoured those who are faster over the shorter distances.
As far as I know it was done that way to make it mathematically easier to figure out.
Anway Stig (James), get joined up and stop your complaining lad! Leigh reckons he can kick your arse anyway???
Thats true, all I ever hear Leigh saying is I can beat Stig on the hills, I can beat him on the flat, la la la la ;-)
Cheers Lee, I suppose a lot of the time it wont have an effect on the result anyway, only when two riders are so close as Chris and Richard.
Look forward to seeing you fellas at the Mercury thrashing this Thursday :-)
