Only the Fe seems to have any significant shift in ppm directly attributed to duration of exposure. The other metals (Al, Cu, and Pb) are all so low that it's a moot point to discuss them, regardless of which sample you're looking at.
I agree that there is more Fe wear per mile with the Delvac, compared to the Amsoil. But Byron is looking at more than just the wear in regard to his total maintenance plan. Cost averages, ease of convenience, UOA costs, etc all play into his decision. Delvac has shown some stunning UOAs; this is not the only one.
Fe wear with Amsoil, based upon an averaged ppm reading was around 1ppm/1k miles (19ppm over 18k miles), and the Delvac ran about 1.5ppm/1k miles (11ppm over 7.5k miles). So, the Amsoil had 1/3 less wear, but it also cost 4x as much money to operate the Amsoil system as a whole! And let's not forget that the Amsoil run WAS USING BYAPSS! Don't forget to look at the soot/insolubles as well. The claim to fame for bypass filtration is lower contaminants, but when you look at the numbers, you can see very little if any advantage in that regard for the Amsoil fluid and bypass system. When you consider those facts, the Amsoil performance is not near as stellar as you would first think. Delvac 1300 and a "normal" full-flow filter did nearly as well as high-end-PAO with bypass, for 75% less cost!
Admittedly, single UOAs are not conclusive. The real knowledge comes from many successive, consistent UOAs. But most people here, (including myself), don't have the money, nor accumlate the miles, to do a true personalized statistical study. In lieu of that, we have to rely on the average information from others in similar situations. Dmax owners enjoy some of the best wear numbers out there for a light-duty diesel truck engine. And there is continuing evidence that shows (for short to moderate OCI duration = less than 10k miles) dino fluids beat synthetics hands down on a cost/wear average ratio. If you greatly extend the OCI, then you can't beat synthetics. But most people OCI way more often than necessary, regardless of base stock of the oil.
Further, where is the benefit to using high end products if you "extend" the vehicle life out past a practical point? Engine longevity is simply not an issue any longer, as they most all will last well past the intended or actual ownership of the vehicle. Wear is so low with today's products (regardless of base stock) that longevity is moot to 99.9% of us! In other words, the higher wear rate of Delvac is still so low that the perceived advantage to Amsoil is nil; neither product has a wear rate high enough to "wear out" the engine in a "practical" life-cycle. So the ONLY savings found in synthetics and/or bypass filtration are in fiscal return, for less oil purchased. And if you can't (or won't) extend out the OCI, then that savings is blown away.
The OP is looking for good wear-protection, cost averaged over a moderate duration of exposure. 10k mile OCIs on quality dino oil will result in excellent wear protection in a Dmax. In fact, it has become so common place that I really don't think that a UOA is even necessary for 10k miles or less. Meaning you can run 10k miles and (if you're a prudent shopper) OCI for about $25 on a Dmax engine. Dino's rule in moderate OCIs; their cost/wear-performance ratio simply beats synthetics.
