ok figured out question 1 but now i have another
it appears that the three csv's have similar schedules but different interleague. csv1 has ALdivision1 playing NLdivision1, csv2 has ALdivision1 playing NLdivision2 and csv3 has ALdivision1 playing NLdivision3 (or something close to that)
the solution i have in mind is to generate three schedule.dat files, one for each csv, and rotate them each year so you'd have rotating interleague play (which rocks). it appears that the intraleague games are all the same for all 3 schedules. so what i think i have to do is import csv1, sim out a season, proceed to year2 which generates a different schedule, and save THAT .dat file as dat1. then do the same for csv's 2 & 3. then i'd have 3 dat files and i'd play the same schedule every 3 years with interleague alternating against each division in the opposite league
does that make sense?
