could anybody explain me why for ranking the next formula is used: 25*(total points)/(10+games)

???

so , game N1 - say player took 5th place and his rank now = 3 * 1 * 25 /11 = 6.82
and game N100 say all games the player took 5th place and his rank now = 3*100 * 25/110 = 68.2

now

if player took 1st place : 15 * 1 * 25 / 11 = 34.09
and for tenth such games : 15 * 10 * 25 / 20 = 187.50
and for fifty such games : 15 * 50 * 25 / 60 = 312.50
and for hundred such games : 15 * 100 * 25 / 110 = 340.91

if player took 7th place : 1 * 1 * 25 / 11 = 2.27
and for tenth such games : 1 * 10 * 25 / 20 = 12.50
and for fifty such games : 1 * 50 * 25 / 60 = 20.83
and for hundred such games : 1 * 100 * 25 / 110 = 22.73

why ? what the reason in so different ranks for just the same level of skills ?

You're wrong if you think that winning just 1 game requires the same skills than winning 10 games in a row.

You can read this thread to see how we came up with this formula
https://www.pokerth.net/community/13-general/13341-new-ranking

The basic idea was that 1-10/(10+games) converges towards 1 the more games you play (see post 7 in the linked thread). With only a few games variance is too high to say anything about a player's skills.

We know this ranking formula is definitely not right, only those players who have 25 ... or more games should be ranked
