Just something of which you should be aware . . .
If someone decides to read the data logs for your circuit, the resynchronisation events will be seen. Each event will have a "reason" code stored with it, so your deliberate attempts to "make the circuit look bad" will be noticed. And that will be a justified reason to charge for an Openreach engineering visit.
If the service works well; if it is doing what you want; just make use of it!

I appreciate the interest in attempting to understand the finer points of the operation of an xDSL circuit but, at times, it can just become an obsession.
