Batting Average

..is there a batting average like function in Sailwave? One that would
give the average place a person finishes, just counting those races
s/he has sailed in?

I use the Rinderle B system to score our series because we have such a
high number of races in our series and also because it levels out the
field a bit more fairly. But I'd also like to score averages for each
skipper. Can I do this in the same series or would I have to copy the
file and score it as a different series?
