The new value at 30° looks to be more realistic, although the drag value (190 N) seems too high compared to the total thrust (360 N), while Cd is only 0.6 on page 45 for PCA-2, Cl being 0.9.
And 165 N at 75° looks to be a (too?) low value for a 4.5 m² rotor disc: the page 45 for PCA-2 gives a Cd of 1.1 (Cd of 1.2 at 90°, full drag, no lift) and a Cl of 0.3.
We would need to calculate the vector sum (on the sketches) to obtain the Ct, but I think that should give a result comparable to the result at 30°, except that the drag component increases and the lift component decreases as the angle of attack increases between 30° and 75° (and even more so 90°). The page 45 for PCA-2 can help for a complete picture (Cl and Cd curves).
