Make a new rating point lower limit.

The rating point lower limit value (=MIR) is a mechanism to set the minimum limit value to the player's rating point (=RTP). The purpose of introducing this mechanism is to prevent completely beginners from matching with former high ranking people.

MIR rules

・All players have 1500 RTP and 1475 MIR (when starting rating for the first time).

・RTP does not decrease below the MIR value.

-The upper limit of MIR is 2100 points.

・MR upper limit value does not change even if the rating above A+ is released.

・MIR does not decrease.

The MIR of a player who has already played a rating match is calculated by the following method.

Use the player's highest rating point (=MAR) and current rating point (=RTP).

・MIR = (MAR-1500)/2 + 1475

・MIR> RTP ➡ MIR = RTP

・1475≦MIR≦2100

If the player's current rating point is lower than MIR, the current rating point will be given priority. That is, the current rating point is set as the new MIR.

(Example) MAR:2699, RTP:1900.

MIR = (2699 -1500)/2+1475 ≒2074 

MIR = 2074> 1900 ➡ MIR = 1900

MIR update

・When the player wins the match and the MAR is updated, MIR +5 points.

・When the player wins the match and the MAR is maximum (2699), MIR + 5 points.
