Tuning with jets, Power valves and an O2 guage

How about THIS:
Running the engine in 2nd gear at 3500 rpms. ALL the timing is in and has been for several hundred rpms.


Maybe people MISinterpreted this?
I wrote that at 3500 the timing was all in and HAS been for several hundred rpms. NOT all in at exactly 3500.
My point in that sentence was to show that since the rpms were WAY past the ALL IN point, the actual CURVE probably isn't the issue. At this engine speed, (And several hundred rpms before it) the total timing is advanced as far as it is mechanically able to go.
I would think that is it took until 3500 to get all the timing in, it might be less likely to ping.
My rationale is that if the engine pings at any rpm point AFTER all the timing is fully advanced, how can the curve be the issue? I arbitrarily picked 3500 to demonstrate that it still knocks from there at WOT.
I am not trying to be arguementative. I am trying hard to understand.
