Krupi I suggested Rads both full open to keep things common to all who test and ensure the conditions are exactly the same for each test. Playing with some in between rad setting will compromise the validity of the comparison as no one else can exactely match any other setting. Keep things simple and constant. I proposed the test and stated the conditions. How about just flying it as suggested. Then repeat it using whatever Rad settings you want. document both.

The purpose of the test is to determine the difference between AUTO and MANUAL prop pitch... nothing else. The claim made by Krupi was that you could achieve at least 50Kmh better in MANUAL. Exact top speed is not important in this test just the difference (if any ) between AUTO and MANUAL.
