I understand what this thread is about, but if it works how Sunsout stated, and I belive him, as he really drops the LVL13s instead only talking about it, it is not an unfair adavantage.
In crafting it is that higher TT input got higher chance to hit really big (thats why gamblers craft Explo 40 PED / click to hit ATH).
If same loot distribution applys to mining (and I believe that is the case), then TT input (cost of drop) directly indicates your max. possible find (multiplier).
So if a drop cost 40 PED (full TT of LVL13 amp ore + enmatter), the system calculates the find based on this 40 PED decay + bombs + finder decay.
If amp is down to 20 PED then the find calculation is based on that 20 PED + bombs + finder decay.
Doesn´t make any difference if the loot find is distributed into 1, 2 or even 3 finds, loot is generated from the actual decay done, and the amp surely can´t decay below 0.
If it could you would have to bring the PED if you dump it into TT, what is not the case
It is just your opinion how loot works that gives you the idea that miners using the amp the way you descripe have an advantage.
In my theorie how loot works, it has absolutely no effect if miner do what you descripe, as loot is generated out of the TT input, and TT input of last drop is 20 PED nothing more. If the find is distributed in 1 claim or in more claims doesn´t matter, the calculation the system does is based on the really spent PED of the drop.
If it would be different, I am sure MA would have done something against it.
MA does nothing, tells me more than you ever will do.
