That's a good idea John. If I take just a first reading to verify the setup, will that give me the sub distance? Or will I have to go through the whole multi-position routine? My receiver needs a minimum of 3 readings before it will do the calculations.
I was trying to analyze this situation (the way we engineers tend to do), and it's probably not such a big deal as I'm making it out to be. After all, the distance setting is used to calculate a delay time in microseconds. It seems unlikely that a difference of a couple of thousandths of a seconds would even be noticeable, especially with a long low frequency wave.
