When the rotor moves with the advance, the reluctor also moves with it. Therefore, once the rotor is setup to align with one of the posts at the same time as the reluctor is aligned to the pickup, it will always be so, regardles of the advance.
I did write in post #43 that the misalignment on my distributor got worse as the advance came in. This was an error on my part as at that point, I didn't realise the reluctor moved with the rotor, so I apologise if this cause some confusion.
Does that help?
