If what you understand is correct, then you are trying to find out the number of full nodes that are working now and measure the percentage of increase in them? In general, it is not possible to know the total number of Bitcoin nodes, but you can know the Listening nodes
[1][2] and you will find a difference in the number.
I think that those who open alternative accounts to receive 14 merits are very successful in using the order of their accounts.
If learning something new means 14 Merits, I have no problem, but I hope it is not misused to create armies of accounts. In general, these farms can be easily tracked.
