I have been analyzing very thoroughly a section of this article:Poker probability (Texas hold 'em) - Wikipedia, the free encyclopedia

Please read through the "pocket pairs" section before answering my question. Indeed, I have tried to replicate the table indicating the probability of facing at least one higher pair depending on 1) your pocket pair and 2) the number of players.

I just realized that the formula for Pma given in the article doesn't make much sense, at least to me. The probability of facing exactly 2 higher players, for instance, depends on the number of opponents.

If anyone can help me calculate Pma that'd be welcome. I'm attaching an Excel file that I created to do so. Here you'll see that I reached a dead end.
