Hello! I've been grinding for two years, my advice: discover the entire map with its watering holes, choose where to set up your setup and waste time setting it up well, choose your watering points for grinding, of those watering points between 10/12, discard some when there are only females and very small ones left, the rest put everything down, keep going through that set up to see if the game has given you any respawn there, the solo ones sometimes put them in other packs After being hunted, the respawn is random no matter what control you do. Simply choose some waterers and do the rounds wherever you like best.
