yes indeed. But I did try out something interesting. I spent all my bonus points on PM regeneration to prepare for my switch to TMBR. It worked out pretty well.

Only 3 bad things happened to me all set:
1. bad reselling during the last 3 days (nothing sold, and I had to log in to sell lower resulting in decay of my PM) - this resulted in a loss of about 4M NW
2. a blunder while playing on mobile (buying ~5m bushels for $194 and selling them for $55) - this costs another 4.5M NW
3. a 10-day old retal that took away 10% of my land while I was stockpiling - I estimated I would have stocked another $1.5-2b more if I had 10% more land. That's another 9+M NW

I timed the food market perfectly (bought all my bushels below $42 and sold all of my food for more than $55). So I would have ended with about 110M if I had a perfect set. But then again, there's no such thing as perfect set as exemplified by the 3 bad things that happened to me haha. There's always a next set though =P
