My report:

I repeated the test of the first CD, recorded at 2X. C2 results:

Max.: 418
Ave: 0.88
Total: 1213

(Quite a bit higher than my first run, as I recall, but I was clueless and focused on C1 and thought things were basically OK until you told me C2 is the one to be concerned about. Who in the hell invented this terminology? Don't they know that the human mind focuses on the first number given?)

I then recorded a new CD at 1X. C2 results:

Max.: 119
Ave.: 0.22
Total: 302


If this were your car, would you proceed with the update, using the 1X CD? I have no idea whether I should be focused on the max number or the total number. If total, then proceding is out of the question. If max, then we are close to your criterion.
