It is very interesting but really too basic. Though it was a direct response to the old "garden hose" posts.
For instance it does not account for the distance difference from one end to the other.
It takes a higher pressure to travel a further distance while moving the same volume of liquid. In other words "at the same pressure" the "end" is getting less volume then the "beginning". (frictional losses and flow theory)
If that pressure drops or fluctuates then the end gets even less comparatively because of the distance difference factor. So therefore in theory the end could be lacking sufficient oil "volume" while the beginning is not.
That's even with out total loss of oil pressure. As in the typical brief oil light flicker and then bearing failure. (Which too many of us have had oil starvation failures
)
Also it does not take into account oiling passage and hole size or possible restrictors. The smaller or more restricted their size the less volume at a given base pressure. (conservation of energy) Also the less pressure after the respective restriction to start with. So a pressure loss before it equates to even a lower pressure comparatively after it as well.
Then add those 2 factors together and you can at least start to see where my thinking is coming from.
