HVN VOR-A -- why such a high MDA?

In fact, the VOR-A is almost perfectly lined up with runway 32;

In addition to the runway alignment issue, there are two other
criteria used for issuing straight in minimums: descent gradients
cannot exceed 400 ft/nm and the course must intersect the runway
center line within a certain distance of the of the runway threshold,
3000-5200 ft in this instance.

The descent gradients seem OK here, so my guess would be the point of
course intersection was out of tolerance.
