I'd honestly be okay with reducing it by more than 7.5k. Mining should be dangerous, and right now its incredibly safe. Just stick a core 1 or 2 POB in the field, hug it, and dock up whenever red appears.
This doesn't solve that issue, but its a step in the right direction towards high risk high reward. I'd certainly like to trial it at the very least and see how it goes. This ultimately falls mostly to @Xalrok and @Karst as system and balance lead respectively.
