Yep, the old one sounds wrong. A 5 minute max effort is required prior to the test. Looks like they’ve added random riding to make it up to the hour, as most people would find a 47 minute workout ‘wrong’!
Power targets should be guidelines and these tests shouldn’t be in erg mode so they’re largely irrelevant. If you’ve got a goal in mind then watching the average for the interval might be useful though.
