Toe varies by room and system. Try no-toe, slight toe-in, even trying radical crossing of toe up to 10" crossing in front of the listener - - would have never believed it until my local 53-year-in business dealer showed me with a few AudioNote systems. The differences and results can be quite amazing.
Try all positions. The generic methods and formulas do not account for your room, just try it all, listen, take notes for each position. My setup has barely any toe-in, and sounds best like this, for my room and system. You do need to learn to trust your own ears in good time. Take your time, try each position, listen carefully.
