I'm concerned that the 2-year setting isn't working for you. That's intended to do just what you're desiring. Shot in the dark, but where are you in the season right now? If you've not rolled over yet (think that's Jan 1) then might try setting those to None and after the rollover, go to 2-year. That 'should' leave you empty on Jan 1-2, make the change, and then the 2-year data should start collecting.

That failing, which I hope it doesn't, I'll revisit the .dat files later tonight. Deja Bru has done a lot of experimenting with message.dat and others. He might have a thought as well, but that's my first off-the-cuff response to address it, Orc. Let me know.
