If I interpret this correctly, SB was deemed non-compliant, even before the performance part of the evaluation, because SB didn't provide high enough fidelity information of the design. The lack of detail is not surprising as they probably couldn't supply it due to delays and shortfalls of the SB-1 demonstrator program. If it had made it past architecture evaluation phase the SB bid would have been found inferior relative to speed, range, size, and most likely cost.
I did like the slap down on no longer being an interested party.
