The stuff that dreams are made of...
So I think you only get the max free points for Tutor if he is the first occupation you take, right? If you choose Tutor for carryover and you've already got two other carryovers, they don't count so you get a max of 4. So I always quit and restart the solo series until Tutor shows up in game 1.
I just took a solo series to 36 games (target score was 95 on the last game!) with:
Lord of the Manor
Woodcutter (not my favorite but I got tired of waiting for Hedge Keeper to come up)
If you're going to play until the target scores are that high, Seasonal Worker really helps. If not, I agree you can live without him if your starting food is at least 6 food, and the bonus points occs are your best way to achieve that.
I will purchase a hat so that I may tip it to you. Amazing!
