The fasting blood sugar level (F) and the post prandial blood sugar level (PP) of a patient was monitored for four weeks W1, W2, W3, W4, and the readings (in mg/dl) for the four weeks are as follows:
F/PP: 170/220, 150/180, 120/150, 90/120.
These have been presented through a bar graph. The normal rangeis considered to be:
F/PP: 70 - 100/100 - 130.

During which week was the fasting blood sugar level of the patient approximately 115.4% above the upper limit of normal pp blood sugar level?
