I really appreciate the input and assistance. It definitely makes for a list of better prepared questions, and there is only so much my research skills can uncover. Opposed to making a new forum, I am going to continue on this forum with updates

.
Update:
We did receive the extension, as the attorneys' office contacted the PEBLO, insisting that the deadline was unreasonable for the circumstances.
After talking with a couple of attorneys provided, the spouse received answers on most of his questions. Some of the answers he didn't like to hear, but some were reassuring, and in my experience that means the information is likely sound. He wrote a statement on his own behalf, and I edited to remove some of the overt anger. (Once again, the idea is to maintain professionalism to the hilt, even though the battles are wearing both of us down). He opted to take the advice and not challenge the findings at this time, and if needed he will challenge them at the PEB level.
His knees which were the original referring condition were found to meet standards if modifications were made. This actually was surprising because the NARSUM writing doctor disagreed with his surgeon at this time. The spouse was informed that the two doctors were likely looking at it with different standards and that is the reason for the discrepancy. The NARSUM doctor looking at the possibility for improvement; the surgeon looking at the need for future surgeries.
He is an insulin dependent diabetic which was found not to meet standards. There was no solid way to challenge this, because every attempt to remove him from insulin has failed. The oddest part is, the diabetes arose suddenly while he was in the process for the knees, and if the process had been timely the diabetes would have been a non issue. He was told there was no way for him to remain in the service, and well this was something he has known and has had to digest since the diagnosis. He is not happy about leaving the military, but as several retirees of various sorts have pointed out, very few are happy to leave.
The language of the medical board documents that had him concerned, are indeed standard language, and to anyone's knowledge, they did not have far reaching ramifications. This was indeed a relief.
The timeline at this point is at least another 4-6 months to await ratings and such. He was given a best guess by the attorney, but as it is just a guess it is no guarantee. The spouse has been instructed to bug the tar out of whomever will listen to get the extension in place until it is determined when his separation will take place.
The PEBLO has been notified of a trip upcoming that will put him out of our home state for about 2 weeks around Christmas. There appeared to be no problem with this particular trip as it is scheduled during a time many are on holiday exodus.
So I am hopeful that there will be fewer hiccups in this waiting period than in waiting periods past.
