Pokémon GO IV management & GBL analysis
Is this the one
to power up?
IVs. Ranks. The actual stats behind them.
GBLBOX helps you decide what to invest in,
starting with a single screenshot.

Rank and battle results
Rank 1 can lose
to rank 76.
Same Feraligatr. Same CP 1,499.
A higher rank does not guarantee a win.
Here, rank 76 has a higher actual Attack stat. Its Shadow Claw deals 5 damage instead of 4. This is why it helps to look beyond the rank.
