Empirical legendaries occurrence in ultra crates

So, well, I opened 100 ultra crates today.
I did not screenshot em, and here is the number of pieces, I counted legendaries only ('cause am lazy), and there is no chance that I misscounted by any number ('cauze am so precise).

Number of ultra crates containing a certain number of Legendaries (L):

35 with 0L
42 with 1L
16 with 2L
5 with 3L
2 with 4L

Total: 97 Legendaries in 100 Ultra Crates

So, nearly 1 legendary for every ultra crate (97%).

You might want to know that among those legendaries, 2 were upgraded (an Illusionist+ and a WaterElemental+, obviously counted as two Legendaries each).

Finally, those 100 ultracrates were worth 5000 rubies, around 17 000 000 coins at today exchange price (but you may not want to convert them, as that price would go up by 5000). I did not count the other rarities precisely, but I can assure you that many of the 2000 units I got were epic (around 500 to 600). Because we know that occurrence of epic in basic boxes is around 3%, if we had opened 17 000 of them (100 ultracrates = 5 000 rubies = 17 000 basic boxes at current price) we would have got around 500 epic, so maybe just a bit more (or maybe the same).

So my conclusion is that ultracrates are absolutely worthy for legendaries (double chance then basic boxes -actually not double but just around 15% more, as explained in the p.s.) but are worth for epic as much as basic boxes. Obviously ultras are not good for rares and commons. After my words if rubies value will increase, I would be very satisfied of that (the reason is yes).

Imagine if developers read this thread about legendaries occurance in ultra crates and say: "oh you got us, now we chang'em". Quite funny isn't it.

p.s: I made a mistake: because of the 0.5% circa Legendaries occurance in basic boxes, with those a legendary is "paid" around 200 000. We know that in every ultra crate there's a legendary (97% chance circa), and 50 rubies today are worth around 170 000. So at the end we can say that, given a certain amount of money, there's a little chance advantage with ultras (around 15%, still interesing). Obviously, because the gap isn't that great anymore, we actually need more studying experience on the subject. I'm so sorry for the mistake.
