I personally don't notice offset changes that small on foot yet so I can't figure it out for sure myself.
Almost. Because of step #3 in my method (subtracting 0.003 seconds to account for the sound travelling to your ear), you could essentially add
0.009 seconds to a song's offset if it was synced to a global offset of 0.000. But otherwise yes, you have the right idea.
At lower skill levels, a 0.012 second offset discrepancy doesn't make a huge difference. A player who gets, say, ~90% on medium charts certainly wouldn't notice the difference. But if you're capable of, oh I dunno, full comboing 9s and passing some easier 12s, that's a different story. I'm not a great player by any stretch of the definition (I've passed a couple 14s and quadded a few easy 9s), but if a song's offset is wrong by 0.012 seconds I will do insanely shitty on it. But then again, I'm an auditory player and not a visual player. Most good players can FA just fine even when song offsets are slightly off.
Also, different players will often have different ideas for what feels "on sync" for them. There are people who think my method feels a bit early and others who think it feels a bit late. That's why I present this guide saying "Hey, this is just what works for
me. Draw from it what you will." The most important thing with syncing is to just make sure files don't
drift.
