Again, the Vittoria testing.
Note the rolling resistance curves presented show that you lose fewer watts by inflating your tires to 100psi than at all the other lower pressures tested. So if hookless were to be counted as a performance road solution, then the system should have the ability to handle these pressures, plus a healthy safety margin.
You again reveal your complete lack of understanding of how tire pressure works. the BRR test is a drum test, which means they do not test the tires with a rider riding a bike. Now as it happens, the rider part is actually somewhat crucial to the whole bike riding experience so we can't just use non rider data.
Fortunately some new testing methods have shown that if you put a rider on rock hard tires, their rolling resistance is going to go up even on velodrome parquet. Low enough pressures on first world roads are surprisingly low. Unfortunately for you, a fast bike is going to feel slow, because a bike that feels like a hitachi massager is wasting energy to produce that massaging vibration.
