Distance vs. Frequency of Access
Frequency of access dramatically decreases with distance.
It is maximum at about 50 cm. If you see a circle origins you, you see your coffee-cup is in the circle with radius of 50 cm. The frequency is half of maximum at 100 cm, that is, length of arm.
To make increase productivity, pen and indexcard should be within the 50 cm circle.
