ANSWER:

6 points

EXPLANATION:

Original readings

120, 121, 122, 125, 126, 126, 129, 132, 132, 135, 137, 143, 143, 145, 148, 153, 153, 154, 164, 164, 173

The median is the 11th number (137).

Additional readings added

120, 121, 122, 125, 126, 126, 129, 132, 132, 135, 137, 143, 143, 145, 146, 148, 153, 153, 154, 158, 164, 164, 173

The median is the 12th number (143).

I'm not sure exactly what it means by 'points' but I think that means 143-137, which is 6 points?
