Champion girls and 5th tier lvl on any boss

[SesGangsta]

Hello,
Is the last tier on any boss in "Champions" a guaranteed 20 affection or just a chance of getting it?
 I think you may have changed the affection system a while back, making the 5th(last) tier of any champion give 20 shards for the respective girls. 
I think that before you'd randomly get the girl with 100% shards immediately but now it's guaranteed 20 every time you get to the last lvl of any champion, from what I can understand?
The problem arises from switching to this system mid-way since the very last bosses are quite difficult and slow... I already have 3 full levels on the "Sky harbor" but the girl there is on 0% which means that I should have 60 shards already instead but I'm on 0 which makes me think that you've changed the system recently or mid-way... Or the Shards are random?
This is not an issue for the first level since that one is easy, my progress on "Morning Wood" is lvl 14 but on the "Sky Harbor" it will be really difficult to start from 0 at level 3... If my understanding and math are correct I'd need to get lvl 8 to be 100 shards, that is if what i'm saying is correct and 20 shards .

I hope I understood everything correctly, is there somewhere I can get more info on the systems of last tier champions and % of chances maybe?

Don't mix event girls on Champions - 35 Shards with a 50% Chance from stages 1-4 - and the Champion girl at stage 5!

At stage 5 there are 7 Items and 1 girl avalaible. If you beat the champ at stage 5 and fullfill the round (so the counter at the start of the got +1) you have a chance to get one of theese 7 items or 100 shards of the Champion girl. After this, what you get is out of the pool and at the next round the lasting items/girl are available and so on until you beat the champ the 8th time at stage 5. In the 9th round and all following rounds stage 5 will give you 10 kisses.
