Enable training to start within 24 hours. I don't always start with my training at the same time. For example one day I might do it at 6:30 and the next I might start at 5:45. However if i start earlier one day then I have to repeat yesterday's training. If it were to let you do the next training day after 12 hours that would be better - or even 20 hours. It's a bit of a pain having to wait to do the next day's training as I like to do simpleology training and start my day before I get going
