I don't believe this to be true. If I did the math correct there was 750 nonresident either sex. 689 went to people with 1 pt or more leaving 61 tags for 0 points.
I would prefer low fence. But after last year going after blackbuck and oryx in low fence, I honestly don't think it matters for most exotics. Just trying to have a little fun in January besides ice fishing.
