[2021] For the folks that work 9 to 5, what was your highest league rank while maintaining that job?

I am curious to see if you can actually make challenger working a 9 to 5 job, or is there a hard limit where it's simply not possible to go further due to time limitations. Obviously, you can still play 10 hours of league a day (good luck with your health), but what about those that have 1-3 hours a day to play. What was your highest rank while maintaining a 9 to 5 job? Is time spent on the game more important than talent in this game?
