[Super strength] Do characters with enhanced strength have trouble telling apart the weight of smaller items?

I was thinking of Superman.  He can lift boulders, cars, ect and toss them with ease, but does that huge strength make it difficult to tell the difference between 5 and 10 pounds?  How about weaker, but still strong people, like Spider Man?

The general rule of perception is that humans can notice a 2% difference in quantities (TIL...).  If you can press 100 lbs you should be able to notice the addition or subtraction of 2.  So a superhuman who can press 100 tons would theoretically have difficulty distinguishing those same two pounds.  

In practice that doesn't seem to be the case though.  Superman has equally fine control over a baseball and a tank.  This may be due to a lifetime of practice.  Those with newly acquired powers typically go through a phase where they "don't know their own strength".  In time, however, they usually adjust.
