Its not a 10 minute tip… 
Add one to the erg 4 life for me. I tried targeting power once and went very poorly (could never really hit the right wattage) and the frustration level would make it much harder to be consistent in doing workouts and wanting to do them. I kind of agree with them that RPE being dialed in is great and probably needed to be great but feel like not everyone has that. Its kind of frustrating when people talk about RPE being useful to ride at set levels like its easy for everyone to learn just cause its easy for those who do well. Should I assume everyone should understand computers like I do cause it comes easy to me?
Though do like the mixed mode method that allowed it easy to go hard for very short intervals and wish trainer road did that:
