Sort by Most Mastered is broken

The games on the first page of Single Player Games Sort by Most Mastered (https://www.novelgames.com/en/single-player-games/sort-mastered/):

Bouncing Balls
Missionaries and Cannibals
Bouncing Balls II
Wolf, Sheep and Cabbage
Wild Wild Taxi
Pool Practice
Social Distancing
Tapa
Spines

And the amounts of users that mastered these games:

1055
121
295
217
176
410
20
926
3

This sorting doesn't work! Spines as the least mastered game is literally in first page!

@Piotr Grochowski , your numbers seems wrong, where have you got those numbers?

https://i.imgur.com/hZa4DbN.png — ranks 1—1055 are users who have ever mastered Bouncing Balls, ranks 1056 and up are users who haven't mastered it.

@Piotr Grochowski , I see. The sorting is not based on the number of users who have got 5 stars, it is based on the total number of stars got by all users.

Is there any way to buy additional sorting options with coins or with real money?

Why can't "Sort by Most Mastered" be called some thing else like "Most Stars"? Spines is very hard to master, but yet it is still on the first page of "Most Mastered". Spines is actually one of the "Least Mastered" games because ONLY 3 PEOPLE GOT 3 STARS.
