Understood. But, 3.8 is symmetric G's; there isn't a published unsymmetric (rolling) G limit. All that is known is that it is less than the symmetric G tolerance, the aircraft is not stressed for to withstand 3.8G's in a rolling pull.
If he was at red line and pulled up abruptly, he clearly exceeded the airframe limits. If he did a rolling pull, he exceeded them to some unknown additional extent.
It will be interesting to see the investigation results. He could have easily pulled the wing off a aero time airframe....
