Based on your comments about your location, I found one that seems to fit which gave the following NM values (using the interactive map feature) for different heights:
WVNY NM:
5 ft, +0.6
6 ft, +6.4
7 ft, +6.1
8 ft, +5.8
9 ft, +5.6
10 ft, +5.3
13 ft, +4.8
15 ft, +4.5
20 ft, +4.0
30 ft, +3.2
40 ft, +2.8
50 ft, +2.4
100 ft, +1.7

tvfool report now:

CJOH analog 8 is now digital on 13.
WVNY terrain profile:

He had a lot of factors working against him:
1. Weak WVNY signal in the presence of another local VHF-High channel (analog 8) that was much stronger
2. Co-channel interference from a local channel also on 13
3. Reduced ERP from WVNY because of its directional transmitting antenna
4. Curvature of the earth blocking the WVNY signal 88.4 miles away
5. Terrain interference from hills
