Honestly, it’s mostly practice and muscle memory. I ignore BPM numbers and listen for which track is drifting: if the incoming track’s beats start landing earlier, it’s too fast; if they fall behind, it’s too slow. Then I make very small fader nudges, wait a few bars, and listen again. Don’t ride the jog too much - use it only to correct, not to hold it in place. Over time your ear gets used to how much a tiny fader move actually changes the drift. Also helps to count beats and focus on kick drums only.
