FitLinxx #1

The next chapter in my fitness saga.

FitLinxx #1

OK, well it’s only the third day of the month, but it’s kind of cool to be on top, even if for such a short time. It’ll be interesting to see if i can maintain it.

Also, I’m not an expert in statistics, but I’m puzzled how one can be ranked #1 and only be in the 94th percentile – shouldn’t #1 be 100th percentile by definition?

  1. I know I am replying to an old post of a year and one half ago. However, I have recently started using Fitlinxx and looking at rankings. In my experience, the percentile statements are always very inaccurate and do not make any sense. This is a bit annoying and perplexing. I have yet to make any sense out of the percentiles that FitLinxx gives or to know why they are so inaccurate. For instance, for this month, March of 2009 I am ranked 3rd out of 11 males in FitPoints in my age group (40-49) at my local YMCA facility. Since 5 out of the 11 males or 62.5% of the 11 males have FitPoints below mine, that would technically put me in the 62nd percentile. However, FitLinxx says that I am “in the 88th percentile based on males within the ages of 40 to 49”.

    According to the Merriam Webster online dictionary a percentile is “a value on a scale of 100 that indicates the percent of a distribution that is equal to or below it”. For instance, if you had the highest test score on an examination out of 100 students who took a test, you would be in the 99th percentile. This is because 99% of the scores are equal to or below your test score. Technically, there is no such thing as the 100th percentile – it does not exist. In another example, if you took a test with 10,000 other students and you got the highest test score out of the 10,000 students, this means 9,999 students or 99.99% of students got a test score lower than you did. This would put you in the 99.99 percentile.

    In your specific case with the FitLinxx points, there were only four other males in your age group to compare yourself with for September of 2007. Out of five males in your age group (30-39) at your local facility, your score was higher than 4 other people, or 80% of the people. If my understanding of percentiles were to be correct, this would technically place you in the 80th percentile for your age group. In your case (as in my case), I do not think the percentile is particularly useful or meaningful anyway, since you are comparing yourself to only four other people. The bottom line in your case is that you have the highest score – you are top dog in the ranking.

  2. It’s very possible that the percentile does not follow the variables in which you have searched by… Ie you are number 1 when ranked against other males within the age group 30-39, specifically. What is your facility ranking when compared overall? This might shed light on the proposed inaccuracy.
