Tanimbar,
I actually don't know as I am not involved anymore.
I assume (dangerous!) that R-R has been looking into all aspects of the systems, including the FADEC software.
From what I have read and memory I would not point the finger at the software myself as all the reports state that it functioned as designed, demanding more fuel when the reduced flow was detected.
I won't post more here - I too think this discussion is not news and should be tech log, I only wanted to clarify the software process.
VnV...
