The error looks like much less than a mile to me. At any rate, the holding pattern does not seem to be plotted at the VOR but several miles south. But it appears to be very close to the extended centerline of the runway.

The ADS-B offset looks pretty close to a mile to me . It's highly likely that a similar offset applies to the published track of LM2933 in the hold, but I agree it's still not enough to put it over the VOR.

Then feel free to ignore it, we'll continue the discussion without you ...
