Why should meeting invitees select at least 3 times?

For group meetings, invitees are prompted to select multiple times to give the group the best chance of meeting at a time that works for all. 

CalendarHero helps meeting creators add more automation and intelligence to the meeting scheduling process - especially for group meetings. From the meeting acceptance interface invitees can easily select a date and time based on the meeting creator's availability.

For group meetings, invitees can see what times others have already selected - and are prompted to select multiple times so that the group has the best chance of meeting at a time that works for all.
