I find reviews at SS exasperating. A whole batch can come back either passed or failed. As different as south and north. Last batch all but a couple passed. Great. Last batch all but one failed. Never consistent. It's a numbers issue. They have to fail or pass so many. That's my only explanation. Luck of the draw which part of the cycle you are slotted in. I just keep re-submitting and they can be accepted.
