Hey Trainers!

So I am curious about the science behind GAP and why it is such an amazing place to catch Pokemon. I was told the following, but I am not sure how much of it is true.

• The more players, especially higher level players in an area, the more pokemon and rarer pokemon spawn.
• Central Park has been designed in the game to have a lot of diverse pokemon, the lures increase their draw to GAP.
• GAP itself was designed to be an area with a vast diversity of pokemon.

I am starting to lean towards the idea that Niantic designed CP and GAP to be a diverse pokemon area and the lures just amplify the number of pokemon in the area. Why? Because even when 100 players are in Union Square, for a meetup for example, you barely get the diversity and number of pokemon that youwould get in GAP.

Does anyone else know?
