I did read it. I've read many "white papers" and have written a few as well. White papers aren't science, they're advertisements that look like science. Calling them a study does not further validate them.
Putting notarized affidavits on the tail end of studies doesn't make them unimpeachable, especially when paid for by a singular participant. I deal with ANSI verification programs performed by NRTL's and I see all sorts of pressure brought to bear by the larger companies to fare well. I've seen first-hand where results were influenced if not downright bought. I've also seen first-hand where estabilished National Consensus Standards were interpreted very loosely.
I'm not suggesting wrongdoing on anyone's part. I'm suggesting that studies like these need a contextual frame of reference. What you offer there is not a "study". It's an ad. It lacks completely any explanation of methodology. It also fails to clearly identify the testing entity and its relationships to the companies whose products are being tested.

So nothing's changed. Good.
I've always been partial to Mobil1 and Wix, probably more out of habit and sucessful results than any real science. Now I have the situation of having a drive that the manufacturer is recommending Royal Purple and willing to put a warranty on. I'm a fairly confident guy but I suppose I have to defer to Konrad when it comes to what works best in their equipment. at least for now.

I'm looking for information and recommendations for Synthetic engine oil for a marine endurance race (gas)engine. I've found overwhelming information for automotive applications, however most automotive oils have now lost much of their vital additives in order to meet emission standards. And marine race engines see much more extreme conditions than any automotive race engine.
I currently use Joe Gibbs Synthetic Racing oil and thought I was happy with it until I disassembled the engine after it had been sitting for a couple of months and found significant amounts of rust on the piston rings and a little at the top of each cylinder.
In my preliminary research, I have only found information for Amsoil marine oil that is suppose to be specifically designed for marine use, but no information on its levels of ZDDP, Zinc, Ca, Mg, Moly, detergents, etc.
I'm curious what the Professional Offshore racers use and recommend.
Thank you in advance for your time in answering.

that do not necessarily help with corrosion. Gibbs, Lucas etc. Some even cause the motor to run a little hotter. Oils intended for Motorcycles or Marine so far are exempt from restrictions imposed by the needs of emission controls, hence the list you see posted by Pismo10.

Amsoil 20w50 in the engines (Or M1 15w50) and Amsoil Marine Lube in the drives. I have run M1 Synthetic gear lube in my drives before, but now I stay away from it because non-Marine gear lubes do not emulsify water, so the water collects at the bottom of the drive causing corrosion issues and lubrication issues.
Compared to other marine gear lubes, Amsoils fully synthetic marine lube is actually quite cost competive: I have not purchased any this year but IIRC its about $6 a quart- compare this to Quicksilver lube which can be 9-12$ a quart.
