Any idea what the drop rate is on the calendar champ?

Anyone know what the drop rate is for the higher star champ in the monthly calendar champ crystal?
I’m 0/10 on getting the higher value champ from the calendar since I started playing, and while I get RNG it is starting to seem unlikely the drop rate is similar to the legendary/ultimate etc. 80/20 drop rate.

Since uncollected now Cavalier all 4's
Sorry I realize that I'm not giving you a percentage
I don't care how absurdedly low it is; I only view the crystal as iso and shards, anyways.
So, 0% to get a 5*
Rare 2* would be cool and I need Level Up fodder. No 2* left to max and nearly all 3* maxed as well.

So 1 in 54 odds for me.
Response in those seem to be about 3-4% chance at the higher star version of champ.
