So i'm new here and to the guitar and i thought it'd be cool and informative to get input from others on when you started playing, how long it took you to start really changing chords smoothly, how often you practiced leading up to being able to get effecient and smooth at changing them chords, and how long you've been playing?

Me? I'm 50 and just starting the journey. I can say this so far, i've gained an even greater respect for those who can really tear a guitar up!
