[2020] Season 10 Rank RP Gain-Loss

The patch notes say that:

" The method used to calculate RP changes for Ranked matches has been reworked to improve the player experience and reduce fatigue.

• The overall pace of gaining/losing RP has been greatly increased to reduce grind and based on performance compared to the player’s current Rank."

But it seems like the max rp gain and loss is +-39 which is the exact oposite of what the patch notes said. Is it a bug or it is broken on purpose?
