@maprik ,
A couple of us are meeting at each other's place soon. The way we are going to do the sessions are - have 2 more chairs and switch the places with the center sweet spot.
Reasoning:
365 Days = 100%, Listen together Days = 5 (just a number), which is 1.4%.
Is it really worth "getting a sofa/love seat/change speaker positions/etc" for such a small % number? You call.
