Exact position depends on the angle of leg thrust and chain, which on a Cruzbike (looking at just one model) depends on how the position of the BB and maybe crank length and leg proportions, but it depends also on the riders pedaling style and in what part of the motion they produce the most force and torque.
The position @Randyc3 shows in his photos look a bit as if the position was more fitting to a typical recumbent with the chain running more horizontally onto the chainwheel, but it would also work, if his strongest point was very early in the "power stroke", a position that on an upright roadbike would maybe be around 1-2 o'clock. But it's hard to tell from a picture if just the BB, as we can't really see his body position, like where his hip is and his legs come from, so the direktion of force onto the pedal.
But I think all this merits a dedicated thread for non-round chainrings and I would bet, there is already at least one where all of this is probably already laid out.
