12 High-End Frames in the EFBe Fatigue Test
For those who don't follow the link the carbon and aluminium frames lasted longer than the steel ones in a fatigue test (although you really should read the article for the full story).
For what it's worth the only 2 frames that have failed on me in 43 years of riding were both steel and they both snapped the drive side chain stay clean without any crash involved (thought it was a broken spoke the first time it happened as it sounded like one and the wheel rubbing against the frame was also indicative of a spoke failure).
Of course you show a fatigue test done by and industry lab that would be pro whatever the current frame material being pushed by the cycling industry is at the time. I remember when that same lab years ago just at the time CF material was coming out showed that aluminum was the best and a frame made by Principal was the best of the best. So maybe you should read this site and then make a thought pattern about the absurdity of that series of tests:
