This does not help you that much. There's noise in everything in real life. There's also signal and it's real and convincing if you have a brain and it's not turned off.
The line of evidence that comes from these clocks tends to confirm the results from elsewhere. To the extent you want to say some reliability problems are fatal, tell AndrewC.
He thinks molecular evidence trumps all other lines of evidence, always. Maybe not always. When he needs it.
Your statement is false. I do not assert that. What I do assert is that molecular evidence is much more reliable and believable than suitably arranged bones, especially when many molecular tests come to the same conclusion(s) and the bones are incomplete. And clocks are not a factor in these specific things, 2 + 2 = 4 no matter what time it is.
