Currently every session will be 18 minutes long. This could result in someone doing more than 36 minutes in a day. If, for example, they start a session and then quit (or it errors out) after 10 minutes, then start another session and complete it they would have done 28 minutes. If they come back again they would be given another 18 minute session, resulting in 46 minutes of training for the day.
We should make every session 18 minutes long unless that would result in more than 36 minutes of training for the day, in which case we should make it only as long as necessary to reach 36 minutes.
