My other theory is that inadequate hose length and engine vibration/shifting under persistent heavy throttle on/off is causing the hoses to slowly work themselves loose. This is the second case of a hose coming loose in a setup with short hose lengths.
While I think measuring oil pressure at the level of these hoses would be very helpful, I think everyone needs to ensure adequate slack in these hoses (just an extra couple inches). Finally, a true stainless steel hose clamp that can be screwed down may be a good idea rather than zip ties.
