Soreness doesn't indicate anything other than a lot of muscle tissue damage.
Feeling a little tight/stiff the day after a workout is normal.
If its painfully sore, you did too much.
Honestly, I know when I leave the gym if I worked out poorly, average, or really nailed it to the wall. I don't have to wait for soreness or lack of to know I did or did not put in the effort at the gym.
But again, being really sore means you over did it and need double time to recover.
