That's actually fascinating. I saw the data - and was impressed with Aidoru then too lol - but you seem to have drawn conclusions better. Out of curiosity, how does farming Expert compare to Ultimate? I could only do Ultimate if I had a +35% to +40% element borrow, otherwise I was only on Expert.

Also, how does Ultimate equate to net gain on Half-Elixers? Are they droppable? Or is it just that the gold-chest-drop ratio is good enough you don't need to use any at all during the event, and thus can 'gain' via the 2-per-day?
