Why do I lose hundredths when summing elapsed times in a pivot tab

[pbv]

I am logging individual race times by person by date by race. I am
formatting these as elapsed times using the number format [mm]:ss.00, which
works fine. However, when use a pivot table (as a step toward graphing the
times), the pivot table rounds the elapsed times to the nearest second. I
would like to display the hundredths in the Pivot table and in any related
Pivot Table graphs. Any suggestions?

(Assuming you want to affect format of a field in Data area.) In pivot table
view, double click on pivot table field name, eg "Min of RaceTime", select
the button named Number... and select the required number format. This
format should stay even after the table has been refreshed.
