Mileage calculations...

While the survey was limited to 60,000 and Over...I have made an adjustment as to how many miles are used in calculating the weighted average.

In other words for YEARs with HIGH number of riders in the 60+ category an adjustment is made:
2005 gets a weighting of 85,000 for the 60+ category
2006 gets a weighting of 75,000 for the 60+ category

Obviously, if I had to do the survey again...I'd have included mileage categories maybe up to 125,000.
But the above approach attempts to resolve this shortfall.

And...I guess that explains why I never went into market research.
Happy Holidays to all.
