Hmmm.
Hard call, that result so far is pretty bad.
Grrrr to MA for their dynamic and affordable
~ 20 ped per hour average fee service offering.
Yea right !
Maybe a change of activity if it is starting to fall out of your affordability range in the short term.
Spice it with some work on the BP you were skilling and give mining a break for a little while ?
Alternatively ... give this a go,
Mine a few fields you know that hold
primarily lower markup ores and enmatters. Stuff closer to the surface in the 5 to 20% markup range. (10% MU average across resources in that location is probably best)
Around PA or Twins, where there is an abundance of low markup stuff.
The system could be taking so much due to cost of participation balancing
(Give vs take/economic contribution vs reward balancing).
ie. Not enough higher markup items/resources that you have decayed (or crafting failed) to offset releases for the markup value materials that are primarily in the areas your mining at present.
Your TT contribution is there by the looks of it, maybe the markup contribution thus far for the areas your working (mining) is not.
The goal being to release some of those funds built up in your accounting by the system possibly at the rate within tolerance to your decayed markup contribution.
I hope that makes sense,
Anyway GL with it.
