Hi Mr. Bruce,
Keeping the HDB8X's panels pointed in unison to the same direction allows the antenna to work its gain as much as possible. I would keep both panels as they are. Further, WFSB being 8 degrees off is still within your beamwith. Generally on this design, you get about 15 degrees of play if the panels are orientated in the same direction, which you are well within.
As for CBS WFSB. When you start to get below 6 to 7 db in field strength signals especially in 2-edge situations can be extremely fickle and may not show up at all. I would actually suggest for CBS coverage you add a second antenna, an
antennacraft Y10-7-13 high-vhf beam and orientate it to magnetic heading 73 to catch WPRI-TV CBS.

This would require a antenna combiner. The
Antennas Direct EU385CF-1s is a quality unit that allows you to combine high-vhf and UHF separate antennas into one coax lead heading into your home.

ABC network coverage is in the category of "maybe." This is due to co-channel interference. Under normal circumstances WTNH RF 10 would have a reasonable chance of being reliable. However WTNH's strength is at 13.7 db while you have WWDP RF 10 at -13.7db. This could be enough to for both channels to cancel each other out. Or, you might get lucky. It's just one of those situations you have to get something in the air and test. ABC WLNE is weaker and also suffers from potential co-channel interference as well. WLNE likely would not be received reliably.
You can attempt ABC coverage if it is more important than CBS, by orientating Y10-7-13 to magnetic heading 276.
As I see your situation summary:
HDB8X Magnetic 303: FOX (WTIC), PBS (WEDH), NBC (WVIT)
Y10-7-13 Magnetic 73: CBS (WPRI), FOX (WNAC)
You may do better, however just off your TVfool plot, this is what my expectation going in would be.
