Is it possible from Bronze V to Challenger in 1 season then?

It seems , that Riot say YES THATS COMPLETELY POSSIBLE I know some players are pro, but to reach Challenger from Bronze V in 1 season, before reset again? Is that possible? I mean, you can be even a damn Faker, but you cant choose your teammates and you never know who gonna feed/afk . Any maths, how many winning games you have to win? Lets say we were lucky and every enemy team was assumed by elo as harder, but we always won. How many games we have to play and win to get from Bronze V to Challenger ?
