multiple point scores

I hope this is clear. How do I ( easily) manage multiple point scores
for a series/race.
We have 24 races over the sailing season with five separate point
scores per race, I am currently inputting the results into four
different files per race eg.

(1) 1 - 24 Total season handicap placing ps
(2) 1 - 24 Total season fastest time ps
(3) 7 of 24 races are scored as a championship ps ( same results as (2))
(4) 1 - 12 are a first half season ps (same results as (1))
(4) 12 - 24 are the second half season ps (same results as (1))

thanks Neil
