Are those normalized power for the two rides? Or average power? If NP then ignore my post
Though NP is not the be all end all of performance, a 300W x 10’ consistent ride (indoors) versus 600W alternating with 0W in 1’ intervals for a total of 10’ (outdoors) will have the same average power but think of how different the perceived exertion is. Obviously that’s an extreme example but you get where I’m going with this. Unless your outdoor rides were in a velodrome with zero wind, I suspect your NP will be higher than average power. In fact, I wouldn’t be surprised if your outdoor NP is higher than indoor NP for the rides you posted.
