That test method is doing the opposite - it's a parametric method of measuring the Cl(max) of a real aeroplane by observing that Cl(max) normally occurs just before the stall and then measuring stall...

But Cl(max) remains the same regardless of CG position - that's the point. Similarly the stalling angle-of-attack (alpha) also remains the same regardless of CG position. The speed at which the...

Of course that does assume the aeroplane has a tailplane at the back (which wasn't explicitly stated in the question) - if it's a canard you can get an answer for the apparent Cl(max) increase by...
