The review of the addition of nested perfload (in I617161fde5b844d7f52dc766f85c1b9f1b139e4a ) identified some inaccuracies in the comments and logs. This fixes some of those. It does not, however, fix some of the duplication between the two runner scripts. This will be done later. Change-Id: I9c57125e818cc583a977c8155fcefcac2e3b59df
