Not to be rude or anything, but maybe check your calculations few times before you post such stuff, instead of doing fancy post formatting with tables .

I assume you forgot to add bonus stage stamina costs into your math, that is why you get magically nearly double the trophies/stamina other people do.

You are also very lucky with your bonus stages. I got 1/3 on Ultimate, and 4/10 on Advanced. But because in the long run doing 50 bonus stage is not that useful for me, I didn't do most of them.

Now to add few stuff and correct others:

Beginner: Average 988 (65.8(6) trophies/stamina)
Intermediate: Average 1392 (46.4 trophies/stamina)
Advanced: Average 4170 (83.4 trophies/stamina)
Ultimate: Average 4814.4 (60.18 trophies/stamina)

25 bonus: Average 1440 (57.6 trophies/stamina)
50 bonus: Average 4703 (94.06 trophies/stamina)
80 bonus: Average 9386 (117.325 trophies/stamina)

Here are the trophy/stamina based on bonus stage spawn chance:

	30%	40%	50%	60%	70%	80%	90%	100%
Advanced	85.86	86.45	86.95	87.4	87.8	88.14	88.45	88.73
Ultimate	73.37	76.51	79.23	81.6	83.7	85.58	87.25	88.75

So in conclusion, with just your values, running pure Advanced is as good as running Ultimate and its bonus stage with 70% spawn rate.

I myself get a slightly bigger average on Advanced which is close to 4300 and thus 86 trophies/stamina, with that value I am somewhere between 80 and 90% spawn rate for Ultimate to make it viable alternative.
