any more info on that?
A perfect band clamp has uniform radial pressure. As band clamps are imperfect, they tend to produce peak radial pressure at the screw termini, adjacent to the slot. To resist this, you should put the slot in the band clamp on an uninterrupted section of the tube, as this will resist deformation under the abnormal load better than the unsupported edges of the tube slot.
I don't understand this. You know you're allowed to have the clamp slot opposite the tube slot, don't you? In fact, there is an argument that you should have the clamp slot opposite the tube slot.
