Season 20% Loss

[khris]

I still don't get the end of year 20% loss. So season 20 I'm 100 (155) then season 21 I start 80%??
(155). I guess im not training enough to gain the 20% back. How do you gain over 20% each season? Looking for suggestions. Let me guess buy rests and coins... Thanks.

Exact, as:
100% = (155) so the 5* is 150

and after a level the distance of the star is +5, so 5* at +1 level, is 155 points, next level, 160avq, then 165 etc
