Just thought I'd throw the QBA's Catobase out there for a comparison. Sounds like a similar operation; we've played from 1901 through 1932, starting with OOTP4 through the current OOTP6. Takes a little less than a calendar month per season, as we sim 25 days per sim, 3 days a week.
I immediately checked the career Win Shares pages, to compare to our league. I noticed pitchers rated much higher in the NABL, until I realized that they pitch more innings, so that makes sense.
Interesting stuff.
