No it just means someone broke it either you or Big Red :-p
I just checked and it's due to the way we calculate the moving average, it's a 7 day average enough for most people going see if I can't expand on that and make it a 28 day average for you long haulers, basically his average is now bigger than yours Lauren so you can't catch him unless you ADD more power.
Okay just for you guys - only a temp fix as I've not really altered much of the code
but look here:
Laurenu2 Long Range Stats and
Big Red
Not as accurate but still gives you an idea based on the 28 day average not the 7 day.
