Very interesting. Thx for your data! Comparing your tt return (90.26%) with your old data (in old good times 91.7%); the differences are so little. Then, the only problem to our economy is to find MU.

True, and back then was purely lvl 5 amps with a higher MU + MU on finder; still allowed an overall profit. Now I can't seem to pan out from amping so I've decided to take some advice and unamp mine for a while to claw back. Also was much lower prosp/survey level. Times have changed
The MU is still out there, but you have to chase it a bit. With 90% TT returns like you're getting (normal for me too), you need to target at least 111% MU to break even unamped. Going level 5 amps at 103.5% MU, and you need to target >115% average find MU. It's doable, but there are a lot of areas I used to mine in my earlier years that just don't quite cut it anymore MU-wise.

That 74 ped Ares Head must have helped out a bit there.
Going to switch it up a bit and focus specifically on higher MU and not always double drops. Still going to amp for a bit and see how it goes.

So I frequently get very very rough results with indoor mining, I'd avoid it if you're trying to have a good stable return because all of these areas also have tax, in addition to extreme volatility.
