You are right, the common factor for PVK addresses is not just the difference in PVK values.
I will tell you a mathematical relationship between PVK values that can be easily calculated.
The PVK value of address 5 is 21 because address 4 has a PVK of 8, and address 5 is the next first value after 4. So, 21 = PVK 5 = PVK 4 + 8.
Do you understand? If you still don't understand, I'll give you another example. Suppose we are looking for the PVK value of address 7. We know that the PVK value of address 6 is 49.
We understand that the PVK value of address 7 is = to the nearest prime number after 49. The next prime number after 49 is 61.
So address 7 is at PVK 61.
Now you understand?
Satoshi is too busy doing things about gods to be commenting here on the theories of mere mortals.
What you're telling me is that as if I were saying the following.
Address 2, pvk decimal value: 3
Address 3, pvk decimal value: 7
Address 4, pvk decimal value: 8
Address 5, pvk decimal value: 21
Address 6, pvk decimal value: 49
Address 7, pvk decimal value: 76
Address 8, pvk decimal value: 224
Address 9, pvk decimal value: 467
Address 10, pvk decimal value: 514
9 and 10 =467
because 9*10 = (90 + (224 + 76 + 49 + 21 +

) - 1= 467
What I did was create a mathematical pattern, conveniently to get the value I want, but this is just an illusion.
Therefore, I don't see much sense in your explanation.
I'm not one to judge, but in science we speak with evidence.
