I did some formal testing on whether finder decay affected TT returns (it didn't), but I've been meaning to add this to the list too. Basically, same finder specs except depth and see if there's a statistical difference if you are switching between "normal" and deep depth each drop to account for things like TT just happening to be low the time you use the deep finder, etc. Hopefully this one doesn't take as long to test
I'm curious though, what makes you think the hit rate is going to be different because of high MU? Everything I've seen so far seems to indicate depth only affects resource composition, not the hit rate. That being said, I haven't seen really good data yet either way that has a good experimental design to sussing that all out, hence formally trying it out.
Personally I think all is very well balanced out depending depth and this is what I think about that, I don't have any prove to back this up.
My returns are all based on the same area's with the same amount of enhancers, doing them over and over again.
Resource composition is indeed different depending depth, so when I'm in a zone with high MU ores, my HR is mostly lower compared to a zone where there are less or none or when using less enhancers
Maybe I should write that down also but there is no way to prove this I think.
This let's me think that there is a minimum/maximum of TT return /drop you can get (depending gear) and off course this can be different every time (not counting globals/hofs, I count those as an extra) since MA controls this by changing the economics of what can/cannot be found.
Gear also affects what you get, in my case it depends what amount of enhancers I'm using.
Going deeper and deeper gives you also a bigger chance of getting more rare/high MU ores.
This gives me a lower HR cause I'm getting more higher TT resources. MA doesn't care about MU, only about TT. So spending xx in drops, will give you ... in TT return depending the zone and the finder/enhancers you are mining with.
According depth, it is also strange that I only found ruga when using 9 enhancers on my finder and not sooner even when I did that same zone over and over before with up to 8 enhancers and going deep enough to find it.
Minimum depth for ruga is 843 so I should have found it with a lot less enhancers.
There is also the fact that like ruga, some ores are capped.
For instance, redulite I'm finding only with minimum 6 enhancers (and finding more when using 7-8-9 enhancers), I did the test again yesterday in a zone where I mostly find lots and lots of it. I used 4 enhancers and ..... got no redulite..... and my deepest finding was 1048 so more than enough to get some redulite.
So I'll be writing it down next time, just to see the outcomes, could be interesting ^^
If you have any suggestions on how to test all this, I'm listening
