Interesting (not quite the sames results):

His sharpness findings are actually identical to ours ...

And that you can achieve more blur at f/1.4 than at f/1.8 is hardly surprising.

This doesn't define the bokeh though. The bokeh is not about the amount but about the quality of the blur.

Blur is just a function of the aperture and distance.
