I've been doing some research, and have found numerous quotes from Mindark which state that their revenue is derived entirely from decay, and that everything else (ammo, probes, auction fees, etc) is cycled back into the economy - and also that not *all* decay is taken by them as revenue, which makes sense, as one would expect most of they decay from melee weapons and amps to be cycled back into the economy as well. Furthermore, each of the three main professions (Hunting, Mining and Crafting) has its own loot pool, separate from the other two, so probes spent go into the mining loot pool while ammo spent goes into the hunting pool, etc.
So, presuming that the loot pool is in equilibrium and as much is coming back out on average as is being put into it, each probe I drop should on average return the value of that probe, while the decay of my finder and extractor go to MA. This means, if I am mining EnMatter, for instance (using the TT finder and excavator, without amps), I would spend 50 pec on probes, 1 pec on finder decay, and from what I can tell, roughly 1 pec on extractor decay per 50 pec I get back, which works out to ~96% efficiency. So what am I missing here? Is there 6% I'm somehow not accounting for, or is the expected TT return not actually 90%? Where does the 90% number come from?
One might argue that the assumption that the loot pool is in equilibrium is invalid, but I doubt that very much - if such an equilibrium didn't exist in the first place, then MA wouldn't be able to (truthfully) claim that all ammo/probes etc are cycled back into the economy. And as long as such an equilibrium exists, then barring dramatic shifts in the game's economy, it would always be at or very close to that equilibrium, as it would always self-correct toward it.
Another, somewhat related question: if entropedia is to be believed, decay on the finder is the same for both ore and enmatter mining (and doubled if you do both), meaning your decay as a percentage of the value of probes you are dropping is lower for ore mining than it is for enmatter mining, and thus your efficiency would be higher. Is this true?
