In regards to the AoM's numbers and Daddog and SkyRock's correspondence.
A warning was issued about your frame 2 numbers ... FR1 attendance of 7, FR2 attendance of 2, FR3 attendance 9. Also in the previous FSO a similar issue occurred with a FR1 attendance of 2, FR2 attendance of 8, and FR3 attendance of 18.
Both low number frames warranted a warning. From what you have posted Daddog issued a warning and wondered if the results of your FR2 low attendance was do the fact of being assigned Vals. You definitely have the right to dispute that and bring it up with both Skuzzy and Brooke as I believe was indicated in email correspondence.
However, separate, from that fact is that you had a low attendance in FR2 Marianas (under by 3 .. commitment level 7-10 so low of 5). In Husky your commitment level was 11-15 so min of 9 and in frame 1 you were under by 7. Your squad rectified that by dropping it's commitment level for Marianas.
So as you state there are two issues:
1) A warning about low attendance (which I believe is warranted)
2) A discussion about whether the low attendance was do to being assigned Vals.
On issue 2 I would say this is between the command staff of AoM, Daddog, Brooke and possibly skuzzy.
