Critical subwoofer tip

I assume that everyone already knows the importance of phase matching a sub to the main speakers but it’s a little more complicated than simple 90 degrees or 180. The B&W sub that I have has four choices. In every case there has been a definite correct position that can be non standard. My current setup shined at 270 degrees vs the std positions. It’s completely obvious and the other choices would not have been satisfying. 
From my lengthy experience I would want a subwoofer with several phase choices. I personally don’t see how one could seamlessly integrate the mains and the sub without this flexibility. No one asked but i thought this info might be useful to anyone purchasing a subwoofer. YMMV

@golfnutz, great way for adjusting the phase . I learnt it from Barry Oder .
I totally believe in adjusting the phase/timing  to the listening position for the sub and the mains . You can do the same with an av receiver by adjusting the subwoofer distance setting .
I use 2 subs jl audio 113v2 integrated with my magico m3. The rt sub is phase adjusted  to the rt speaker and lt to lt main ,  at the listening position. Changing the phase, the difference is very obvious  as the subs are placed in the optimal position using the crawl method .so the primary listening position is not a null.
I totally agree with the OP .
