Thank you so much for this suggestion and for the pointers for how to do this kind of test.  I was struggling to figure out the proper mechanism and you helped greatly.  I have added two separate tests for tune-cpu instead of combining with the target-cpu ones because I think it's cleaner, but I am happy to combine if you prefer. Just let me know.  Thanks again for your help!
