Can the math formula used for finding the mode mean and range of a set of numbers be used for finding the average opponent rating similar to the one used by chess.com. I'd like to use the correct or most accurate system used for weekly adjustments of keeping track of the level of opponents I face  (I never really play one class of rating it's always varing and to me this is a great way of keeping it to where I at least play my average of players). My theory on it is that Mode can be used in a way of which a certain class out numbers the rest for instance If I play 3 1800 players one 1801 the second 1834 and third 1821 and only one person rated 1303 that means my average opponents rating is 1800 notice how all of the 1800 players were below 1850 I used this to estimate my average to the nearest hundreds even  if it were 1851,1832 and 1812 it would still be 1800 since 2/3 ratings were still below 1850. That's only my theory by using the Mode formula what I'd like to know is how chess.com gets it so accurate  like if you look at some one's profile and it says there average opponents rating is 1634 instead of saying 1600 0r 1700 by estimating and comes's up with an exact number

Punctuation is a plentiful resource, feel free to use it as much as you like.

Also, separate paragraphs are not illegal.

Ok point taken could you give me an actual answer now.

No, I couldn't follow what you were saying, hence my initial suggestion.

I'm basically just saying how I think math can be used to get the average opponents rating like in the statistics part of a chess.com profile

I'm not totally sure, but I think that chess.com simply calculates the average of all the opponents' ratings without any fancy fomulas.

Or is this is an April Fools' thing? - in which case; well played.

Well, that is what math does. Average is a common word for mean. Total all scores, divide by the number you have = mean. What else could it mean?

Thus, #7.
