Hi,

Was trying to use your DB and I found what I think it's a data incoherence...

When you list the rules, i suppose that they must be in chronological order, I'm assuming that (X) rule start date always smaller than (X+1) rule start date, for instance:

R Q 1967 o - Ap 8 0 1 D
R Q 1967 1968 - S Su>=8 0 0 S
R Q 1968 o - Ap 14 0 1 D
R Q 1969 1977 - Ap lastSu 0 1 D
R Q 1969 1971 - O lastSu 0 0 S
R Q 1972 1974 - O 8 0 0 S
R Q 1975 1977 - O lastSu 0 0 S

I fund in the Haiti rules the following section:

R HT 1983 o - May 8 0 1 D
R HT 1984 1987 - Ap lastSu 0 1 D
R HT 1983 1987 - O lastSu 0 0 S

According to my assumption, to keep DB coherence, we should have, in 2nd position something like:

R HT 1983 o - O lastSu 0 0 S

Am I right or is it some particularity that I didn't understand?

Best Regards.
