1. If you calculate based on the M11 or M22, you may not get stress averaging. Or in otherwords you have to average the stress according to the width considered. If the stress is not averaged, in some cases you may end up with stress singularity. Finite element based reinforcement may be very high at this location. Moreover its all depends on how good is your meshing. As 'parhyang' highlighted you have to use wood and armer rule.
2. As for as the strip, new version of SAFE allows you to define inclined as well. You can draw the strip line as per your column arrrangment. it is sipmple to define column strip and middle strip. The strip method consider all the efects and gives you the average reinforcement either for full width or per m run.
I suggest to design based on the strip method. You can model a simple slab and try your own to feel the difference.
