That's approximately the same (or more) what the 90 M Summicron does at 2.50 m (~8 ft) and wide open. Additionally, both, the Summarit and the 90 M Summicron, show a rather soft out-of-focus rendition. These were the conditions, on which I described the 90 M Summicrons' wide open performances. And, I think, that my comparison was not unfair. But, I agree also, that the 50 mm Summitars or Summicrons are more sharp at f 2.0 than the Summarit, and that they separate more shadow details, specially under low light conditions. And I agree also, that the 90 M Summicrons manage high contrasts wide open far better than the Summarit at all f stops. But, maybe all that was a little too much detailed for the original question ?
