X100 that short 77k is quite difficult. If I pump in more armor to reach 80-81k then there is still hope. I'm in the same boat as you but I'm sitting at 83k.
88 left about 81 in 1 day, so what is there to worry about? Just keep plowing and the harvest day will come. The 7x 8x area has a lot of money to feast on. Accumulate - push prices - sell off. That's an endless cycle.
