Make a better match schedule plz

As a team steps into the Final (assuming 5 games in all knockout stages) , it would play 27 games in 7 days . But they will have 24 days off. If it is 40mins per game, they will totally play 18hrs 10 mins. It is less than 40 mins per day( in 31 days). So, WHY DO RIOT MAKE THIS SERIES SO LONG? And every team has no more than 3 match days in knockout stages, so , 14 days off. LMAO. What's is this schedule? 14 days for shopping? And there are totally 15 match days in a month (31 days). Riot unprofessionally extends the lengh of the Championship series. Plz make the series short and logical, both considering teams and funs. Not only Riot's commercial interest.
