Although most time-boxed meetings take the amount of weeks in a sprint into consideration, none of them seems to include the number of team members when calculating the max duration.
What I mean by time-boxed meetings: Sprint Planning, Sprint Review, Daily Scrum, ... - not the sprint itself.
Let's compare a team of 3 to one with 9 members.
According to Scrum we have at max 15 minutes to all answer the '3 big questions' during daily scrum - no matter if we're 3 or 9 people.
Same goes for the sprint review. 9 team members might produce triple the value that 3 do, but again we have 1 hour per week of sprint.
What I would expect is something like max duration of a sprint review = #ofWeeksInSprint * #ofTeamMembers * someHourConstant.
Why does scrum ignore this factor?
