With this, pumpjacks bottom out at 0.2/s, regardless of initial production.

Pumpjacks bottom out at 20% of initial oil production or 0.2/s, whichever is higher. For almost as long as this change existed, I've used a console command to change the initial_amount value so they bottom out at 0.2/s, always (this doesn't reduce the amount they produce initially, it's "amount" and gets set immediately.)

So, I finally rolled it into a mod (for convenience and modded achievements :D)

Yay, my first mod! Okay, my first published mod…
