Dana was testing using resistance, and also using a '67 tank which may be different enough to measure a little different.

Gauge has 2 adjustments on it, and you can do some adjusting on the sending unit itself... This is assuming full up is full in the tank and straight out is half. And full down is empty. Seems rigjt
