So, while a really bad number can be a sign of wear, it's probably too late at that point and a "good" wear report may not be indicative of degraded high-temp viscosity, which is what we care about.

Personally I'd rather change the oil more frequently, a change only costs me ~$60, for the peace of mind.
The gamut of tests include one for viscosity at 212F; they will let you know if your oil is degrading(shearing).

300V does not shear, period. It's also significantly more than $60 for one oil change.
