So as far as mark up ores with amps.... I find their liklihood is decreased and that each amp has a certain tendency to either bring up, or not bring up, certain resources...
I've noticed some resources like spawning in bigger deposits, and those I often do find with amps still just less commonly. I've also noticed some resources don't really like ever spawning unamped above a certain small amount, and then I never see those with an amp....except extremely rarely.
I find it's not necessary a RESTRICTION, it's a reduction in probability. It seems to work differently for each ore too, and change as the economic availability of the resource changes(when they're adjusting something back, which I paid attention due to your posts, I notice I get far fewer amped finds, yet when they're adjusting up, I find much less restriction on amped finds).
I also notice that this seems location dependent, each general area seems to have tendencies to either hit with amps, or miss with amps. It's like amping up changes the overall areas of where resources are made available to offer fewer points of high markup available, but....there are some I can reliably hit with an amp. However I need more data so it's not napkin speculation and such...
I'm still trying to get enough data together in order to have a useful data sample...when I do I'll pm you.
I think that you'll have some interesting questions for me, too. My questions in mining are more along THESE lines, and other dynamics, not TT return or 'where do I find this'.
My questions I had for you in regards to a mining mentorship are all purely 'why does this happen when I do this?'.
If this theory is true. Then there's a sweet spot amp for each location to get best mu.
I am really starting to feel that yes, in each area each amp will get different overall results, though they follow a somewhat predictable pattern(not hand edited 'does this amp work for it?' but related to the amp efficiency).
I also think if you were to get data samples in a list of areas, with all amps tested, then we would see some of the amps are really good in certain areas for certain resources. However if you're say, amped and looking for redulite, your number of places in the game available to you is greatly decreased. I need more data to say for sure, however.
That part at the least seems to be pretty solid. If you take the high TT resources like Valurite worth 6 ped a stone, you're not going to find it easily unless you are amped a bit. There at least has to be a calculation early on determining TT of the find followed by a check on what resources can be given out without being < 1 item.
Beyond that, it's tough to formally test whether caps based on total amount in player hands exist. I've tried a little bit of that with Dianthus, but haven't found anything that really predicts resource availability yet aside from this amped Dianthus case.
I was under the feeling that when you find claims with amps, the calculation of what is to be found might be done as follows.... efficiency reduces this base TT, meaning it's harder to find higher rarity or TT materials, after which the amp increases the claim by a certain amount in order to yield your end TT.
If an amp is appearing to give say, a 10x multiplier, then you might be getting (5 ped TT ore / 5) *50 instead....however once again I need more data to say for sure.
