Different FDW settings provides somewhat different results with more apparent clarity when using a small number of cycles. It can be misleading in many cases. It is very helpful to initially set the delay where the phase tracking looks good for the direct sound, but the final delay adjustment in the AT is best done without FDW active. Including a minor timing adjustment to accommodate the influence of the room in the final setting is a better.
