How is the Crown Level calculated?

If anyone knows, I am curious as to how the Crown Level is calculated. i.e. I wonder why it is it that my Crown Level in Spanish, which I have been studying for quite a long time, is 187 while my Crown Level in German, which I do not have anywhere near the proficiency in, is already 152. The difference in my Crown Levels in those two languages does not at all reflect my relative proficiency in them.

The length of the tree may have something to do with it, as I believe the German tree is considerably longer than the Spanish tree.

[The general crown level is the sum of all the crowns you have earned, so if you earn 1 crown for every skill for a long tree, the total might be higher than the crown level for a shorter tree with a healthy admixture of level 2s among the 1s, for instance.]

We ... used how many times you’ve seen the words in a skill and how many times you got those words right to determine whether to place you at Level 1, 2, or 3. Since levels get harder as you go up, we didn’t feel comfortable placing anyone at Level 4 or 5, since the old system didn’t give hard enough exercises to place into these levels. Of course, if you already know the language very well, this may not be the right level. But, it is still more challenging than what was offered before.

Yes, that may be their (staffs) theory.
But it does NOT work in production as they announced it.

The truth is, that the conversion is part of another A/B test: Simple vs complex.

And their "experiment" miserably failed for my EN-PT tree because of the "simple conversion rule"!
