Are they? How is this determined?

I think Acovea might allow the flags implied by these options to be 
chosen in a more quantitative way. Obviously Acovia should give better 
results when used with a specific code of interest.

Good luck this weekend. I look forward to trying Acovia on my thesis 
research code (and will happily cite your paper).
