Ratings for new players are computed by several different algorithms depending on how new they are.

1.  The very first dynamic rating of a singles player is calculated using the rating of his/her opponent and the closeness of the match.  This rating can possibly be a strike if it is a significant win over a player in the upper part of the level.   The rating system does not differentiate between singles and doubles rating so in rare instances a person whose rating is primarily derived from doubles my contribute to a rating for a new singles player.

 

2.  The second dynamic rating is calculated using the rating of his/her opponent and the closeness of the match.  It is also possible that this rating can be an immediate strike.

 

3.  The third dynamic rating is calculated by a slightly different method.  It averages the two existing dynamics together and compares them to the rating of the opponent.  Then it looks at the closeness of the match to see if it agrees with the compared ratings.  On the basis of that, the rating of the new player is calculated.  It may be slightly higher or slightly lower than the average of the two previous dynamics.

 

4.  The fourth dynamic is calculated like the third but all three previous dynamics are averaged together first.  That average value is compared with the rating of the opponent and the closeness of the score.  On the basis of that, another new rating for the player is calculated.  But this time the rating from this match is averaged with the three previous ratings and that value becomes the fourth dynamic.

 

5.  From this point on, the rating of the player is always their must recent dynamic.  This value is compared to the rating of the opponent and the score and a rating for the match is calculated.  As in the previous step, this rating for the match is averaged with the previous three dynamics and becomes the next dynamic.
