Mine would be like 101, except since that is a table in between us I hit 2 there, and then where 7 and 8 are I take 6 measurements. The more you spread the mic around the more of the room differences it may need to filter. If you can focus on a couple of primary seats, and take more measurements. I also think the 3 inch adjustments are to focus it more, and I agree with that. In the past it was 2-3 feet between mic spots, and now my 7702 preamp says each placement should be no more than 24" from the first MLP measurement. So over time Audyssey has made the placement more strict.
I set the mic up in the MLP and took all 8, the FR was flat and the best I have ever seen. But, it was able to remove all the issue at that one spot, where as the more positions you use the less the filters can do. It got me thinking and experimenting.
A lot of the Audyssey hints here are incorrect, but I am not getting into that with the people in the thread. I have run sweeps with the glass tables in my room covered and uncovered and they were exactly the same, were as some will tell you to avoid those or being to close to them.
I think there is some merit, if you truly only have 2-3 positions, center on them and have audyssey build the target for those 2 or 3 seats in detail. When i get my new amp in I intend on taking one in the MLP, 4 in my chair, and 3 in my wifes. No seat backs, no armrests, no more in the center. My ears are never in those places. Now if you have an 8 seat HT I think you have to spread the wings a little and accept the fact it will be less ideal.
The thing to remember about Audyssey, especially XT32, no matter how many unrelated spots you do it is still an improvement over the raw.
