ohoho yes! That calculator would immerse me so hard. I wonder if some kind of mathematic paper aid might speed things up a little... Not sure what that would look like.
In doing some testing with things, I think the slowest parts for me are the sheer amount of data to generate; so many tables and so many goods to update before actually making any gameplay decisions. When I'm making decisions, I'm having a blast.
Definitely works to help just dive in, you've more than succeeded here. It's a style that so few tabletop games even try, let alone do well.
This kind of this is always gonna have crunch, though, so please don't feel pressure to waiver and dial it down to cater for everyone.
I've got some ideas to hack parts of this system to make it more of a game for me. If I come up with something I'll be sure to post it here.
