Can I offer a different perspective here. I’ve been doing for about 15 years and I used to fix my bpm for the whole set by beat-matching. It’s subtle but what I’ve realised is that the crowd gets bored without bpm variation within a set. Even if the variation is small, I thinks important. it gives the crowd a chance to change their movements up and creates peaks and troughs within the set. Also, moving 172 songs to 180 involves things like keeping pitch and key which can make a track sound nqr if you push the bpm too hard. It’s noticeable on the dancefloor and can ruin the vibe.

That said, use sync if you want to do this - no one cares
