@Riot, time for winrate rise after a buff?

out of curoisity i am wondering how long it usaully takes winrate to rise after a buff. the players who ALREADY play the champ and are GOOD at them, will obviously get their winrate on the champ to rise immediately.

yet at the same time.. buffing a champ usally tend to draw NEW players to the champ because they think "oh X" champ is suddenly OP" and becuase they are just starting the champ and really don't have any idea how to play it. it tends to decrease the winrate of said champ.

yet end the end the winrate always rise after a buff.

so how long does it usually like for the bad players trying out the new champ and doing bad with it to no longer outweigh the buff itself that cased anyone who KNEW how to play the champ to get a higher winrate?

I'm assuming it kinda depends on the buff because if the buff made the champ EASIER then it would probably mean the time until winrate rise would be faster than if the buff didnt make them easier to platy but just made them "better"
