When you raise the RPMs do you get only one timing mark?

Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first.
Life was a little easier when I was just a wrench.

Reason I ask this is because with a lopey cam, very low idle, and/or when a timing chain is worn this can be common with some combinations at idle.
The cam will go forward and back on the slack of the chain it has during idle and the timing will bounce up and down off of the balance weights giving you multiple flashes at different spots. If raising the rpms takes away the multiple flashes at different spots, this is what is happening.
