Has there been study of electrum gain across game modes?

Lot of attention has been paid to rush decks, but to me it makes no sense to look into turns to win if simultaneously it doesn't matter if you get EM or not. AI3 is the fastest grind with card spins in between. Arena is slower and getting accurate data is difficult. Then there's FGs, which provide upped cards on spins, but matches take long time and fail rate is quite high. It is all but clear which of these game modes is the best for electrum gain if you assume card's 'value' is its selling price.

I don't think electrum gain index has been done before. I have an idea which would make value determining easy for AI3 and FGs. Since all their decks are pre-determined, we can calculate the chances to spin each card in deck. Then we can make weighted average as follows:

Value of spins = CARD1 value * CARD1 match in spin + ... + CARDn value * CARDn match in spin

It's also possible to calculate chances to get same card for the first 2.

Cheers mate.

It's a menial job to calculate all those percentages by hand, but I'll do one just for curiosity's sake.
Using the Trainer (http://www.elementsthegame.com/trainer) to determine each card's value and acquisition rate from column P(win card) in 1 spin[%] times 3, as same card can be won multiple times, we get the following long-term average value for Akebono's slot machine:

[6.603 (tower shields) + 0.108 (gravity towers) + 18.242 (elite armagios) + 126.388 (massive dragons) + 6.581 (unstoppables) + 7.400 (titans) + 18.258 (chimeras) + 58.693 (overdrives)] * 3 = 726.819 electrum

It means that over a long course of time the slot machine is netting you an average of 727 electrum for Akebono's wins. Total winnings also account for the actual electrum prize.

If we could do this for each FG and hopefully in some automated form, we could use this data to determine which decks are gaining the most money. Each deck has certain FGs that they excel against and each FG has different value for their slot machine.
