So what's the point of the exercise?

Chances are you would have got most of the matches correct. So what's the filter you unconsciously used to make these judgements? 

When Watson asks how Sherlock Holmes knows this, the detective answers:

It is simplicity itself .... My eyes tell me that on the inside of your left shoe, just where the firelight strikes it, the leather is scored by six almost parallel cuts. Obviously they have been caused by someone who has very carelessly scraped round the edges of the sole in order to remove crusted mud from it. Hence, you see, my double deduction that you had been out in vile weather, and that you had a particularly malignant boot-slitting specimen of the London slavey.
