Re: [DR] Re: [RC] [AERC-Members] Multiday/Single day ride speed analysis - renegade12Truman, I think it would be interesting, and perhaps more informative, to do an analysis on individual riders and their speeds at different rides rather than trying to develop a conclusion from data that doesn't have enough "bottom" to give a valid conclusion. The Top 50 Fastest Rides doesn't take into consideration that the duplicate trails and entrants skewer the results...what I mean, if a rider has ridden a trail multiple times they will be able to improve their speed each subsequent time...I think that is what you see in my rides listed in the Top 50...same riders, same basic trails on the same ranch - trail loops may be in different order but that doesn't change or alter the speed - especially since I get mostly the same riders - I can tell you within a few minutes the ride time of most of the riders before the ride even starts, based on my experience over the years. However, if you took 50 different riders who compete in both multi days and single days and compared each riders ride times in the different type of rides - that would give a better analysis, in my opinion.

The data was based on all riders entering both single day rides and multiday rides. These two categories were then analyzed. The chart was put in there for illustrative purposes so - no conclusion was based on it. The fact that here were more pioneer rides than one would expect was an afterthought and not critical one way or the other for the analysis. In reality there are many of the same riders in the multiday rides as in the single day rides and many of the same riders in many different single day rides. The riders are the constant population that is used to test the hypothesis. Any analysis of this type of data is useful for trying to understand in a more rigorous way that our gut feel facts about the underlying population. The question this raises is why do the multiday riders swear they are going slower when they aren't. Maybe they are going faster they are going faster than they think - that is what the clock says.
