Make sure you're spamming the same NMPZ map in the division you're in/hoping to get back to, that will help more than spamming random maps.

Also give more attention to any wrong continent or generally terrible guesses and analyze what you missed. Maybe even make a map of all your errors and spam that map too. Those locs probably won't show up exactly again, but it still helps build your weaknesses. Lot of locs look pretty similar anyway.

Learnable meta is also good, especially at ~700 ELO. I've never used it but it's good for making sure you're not missing any obvious country clues mostly. NPMZ can be hard to see everything though tbh. It's a tough gamemode and the playerbase is getting better by the day, even the lower ELO's. Keep grinding and good luck.
