I'm only level 11, so i'm not going to use stardust or candies for a while.
I found out how to know my pokemon's IV, through this tool for example.
The pokemons I catch are low level, something between 10 and 250. Is it worth looking emthem up, and IF iif I find a perfect score, should iI upgrade that one ? Or should iI just try to get a perfect pokemon at a higher CP, so iI don't waste stardust on a pokemon i got at CP50 ?
Thanks !
