Has the function of the ability 'Super Luck' changed in gen VII?

Up until now every page has stated that ‘Super Luck’ increases the critical hit ratio stage by one (1 becomes 2, 2 becomes 3, 3 becomes 4), but Serebii has just posted an ‘update’ to the critical hit info page, and part of that states that it now DOUBLES the ratio stage (1 becomes 2, 2 becomes 4, 3 becomes 6). Is this a typo, because the page for ‘Super Luck’ still has the old text

There is also one special ability that doubles the Critical Hit ratio stage (If normally 1 it becomes 2, if normally 2 it becomes 4). This ability is Super Luck and is only known by Murkrow, Honchkrow, Absol, Tranquill and Unfezant and with Togepi, Togetic and Togekiss getting it as their Hidden Ability

Edit: Just to add more complication to the matter, it turns out Bulbapedia’s stage +1 is the same as Serebii’s stage 2. I don’t have Sun or Moon, so I can’t test this, but if anybody can use Absol with Super Luck and Night Slash, not getting a crit even once will help disprove the change.

The mechanics behind Critical Hits have not been changed in Gen VII.They were, however, changed from Gen VI and still remain.

The critical hit boost was reduced from x2 to x1.5 and chance of critical hits at Stage +2 was doubled with critical hits becoming certain from Stage +3.

As for your question, no, the function of Super Luck has not changed. This ability only increases the Stage of the critical hit ratio. Serebii must have suffered a typo. A big one.

P.S. Who uses Serebii anyway? Pokemon Database has got to be the cleanest, organized and simple websites for Pokemon queries out there. Bulbapedia is also amazing when it comes to anime and completely wild facts and trivia on Pokemon.
