With the Mining Revamp: Turbo Reloaded Laser Barge Edition being released a few months ago, CCP made the interesting choice of doubling the ore pull size of all moons. This was in part to counteract the introduction of waste, so that groups wouldn't see an active reduction in the value of these moons.

Of course, what CCP either forgot or ignored is that high-tier moon goo is mined at a rate extremely close to max capacity- if a moon has R32 or R64 ore in it, there is a 95% chance that moon is both anchored on and mined every month. As a result, moon goo prices tended to be pretty stable- while the overall value of the ore dropped when CCP ripped out the regular minerals, the moon goo product was still stable bar rare instances of whole regions burning and resetting the moons for a month or two. High end moons also produce significant amounts of lower tier moon goo as well, further reducing the value of other moons along the way.

Even accounting for waste, it's still likely that we're seeing about 30-50% MORE high value moon goo materials hitting the market. We're starting to see the effects of this pretty clearly on both ends of the supply chain. It probably doesn't help get us out of the HAC meta as HACs continue to drop in price.

Don't worry moon owners.... your prices might hold for now. You just need to mine twice as long in order to get your money's worth!
