Very good point about actual VF vs published VF. There are several ways to quickly get the actual VF of the cable using a NanoVNA but the OP ("Anne") doesn't like posts that go beyond specifically answering her question.

PS
According to last test - my " digital ( other superlatives intentionally removed ) RG6" VF is .66 !
