Baloney or hogwash, whichever you like better! Your test results points to nothing. There is absolutely no way to identify with any degree of certainty which parameter caused dielectric change. Is it wear, or ingressed contaminants, or loss of additives, or something entirely different. And BTW, you did not even try to answer the posed question. Shame on you, cheap peddler!
A.S. Pal, in order to get an answer to you inquiry, you need to be more specific; e.g. which oil is of you interest? Is it motor oil, turbine oil, hydraulic oil, gear oil, transformer oil, or something else? There are no universal limits that would apply to all oils. However, there are some role-of-thumbs out there, but eventually, end-users set their own limits for a particular oil.
