According to the New York Times, participants in speed dating experience an average of 2 in 10 or 3 in 10 matches.
Online dating participants, in contrast, only find a compatible match with 1 in 100 or fewer of the profiles they study.
The time limit ensures that a participant will not be stuck with a boorish match for very long, and prevents participants from monopolizing one another's time.
On the other hand, a couple that decides they are incompatible early on will have to sit together for the duration of the round.
Speed Dating, as a single word, is a registered trademark of Aish Ha Torah.
Speed dating, as two separate words, is often used as a generic term for similar events.
At the end of the event participants submit to the organizers a list of who they would like to provide their contact information to.
