I have over year of speed and the wattage data. I know there are other factors but my sample group using two depth wheels on the same bike with the same set up is about 2000 miles on the same rides. It's about an average 12 watt difference at the same average speed for me on my bike.
Did you measure the HR difference between the two?
Note you didn't say which took less power.
My testing I found the deeper took more effort (reflected in HR) for the same power. Meaning there was core effort that was higher for the larger profile wheels. Time and time again, chose to use 50mm profiles.
