deviations are and what your z score is. Each track and overall would
be nice.

st_dev : standard deviation
av_time : average time
time_tr : time for track tr
st_dev ^ 2 = sum ((av_time - time_tr)^2/ (number of tracks)) for every
track

Actually I think I may have got the theory a bit wrong myself, I don't
know if it works on different tracks, but what you can do is to find
the st.dev. for each track.
The st.dev is the average difference of everyones difference from the
average time for a given track :)
You take everyones best times for a give track and calculate the
average. For each person you calculate the difference between that
average and his/her best laptime. Square that number and divide it by
the total number of persons. Do this for every person and sum it all
up. The square root of that number is the standard deviation.
