I haven't called because I know a read can't be accurate over the phone without body language. Even face to face plenty of things as simple as personality quirks can throw off a read and it certainly isn't so much of an exact science. In the end this is why we do surveillance before and after an interview when possible since verifiable actions are the story teller more than any other evidence.
I won't go farther down the hole as I am already over $250k deep which is much more than I should have ever risked. But after seeing the cycles I expected that to play out once again and kept cost averaging in.
