From Mary's post on the other thread:

"Re: Redress in the second race for Scotty Anderson and Murray Philpott:
Apparently, the RC was a little slow in getting the Charlie flag up at the C mark to indicate a change of A mark. The flag went up after Scotty and Murray had rounded C, so they were not aware of the mark change and were given redress."

That's... not... good...
