IV's etc per Trainer Level
Between levels 1-29, wild spawns have a different stat value per trainer level.
This means that a pokemon with IV 60 CP 500 for a level 15 might be IV 80 CP 250 for a level 19.
This changes at and above level 30, where all levels 30 and above receive the same wild spawn stat values.
Our coordinates feeds post data based on level 30 and above.
This means that if you are level 29 and below, Pokemon from our feeds may not have the same stat values as they do in our feeds.
If you are a donor, you can use #donor-coords-pokego-lower to see coordinates with a trainer level value added and snipe things only relevant to your level.
There is also a /trainerlvl filter for the in-game feed for donors.
