Why does NDRC always raise oil prices?

Principle of gasoline price adjustment: when the crude oil price in the international market rises by more than 4% on average for 22 consecutive working days, the domestic refined oil price can be increased accordingly; When the price of crude oil in the international market falls by more than 4% on average in 22 working days, the price of domestic refined oil will be lowered accordingly. When the price of crude oil in the international market is too high, too low or fluctuates violently, the state will take relevant measures to appropriately adjust the prices of gasoline and diesel.

But the NDRC is a genius. It fooled the whole country with the knowledge of elementary school mathematics.

Take international oil price 80 yuan and domestic oil price 6 yuan as examples:

1. When the oil price rose from 80 yuan to 83.2 yuan, the increase reached 4%, and the oil price rose from 6 yuan to 6.3 yuan;

2. When the oil price dropped from 83.2 yuan to 80 yuan, the drop was less than 4%, and the oil price remained unchanged;

3. When the oil price rose from 80 yuan to 83.2 yuan, the increase reached 4%, and the oil price rose from 6.3 yuan to 6.6 yuan;

4. When the oil price dropped from 83.2 yuan to 80 yuan, the drop was less than 4%, and the oil price remained unchanged;

5. When the oil price rose from 80 yuan to 83.2 yuan, the increase reached 4%, and the oil price rose from 6.6 yuan to 6.9 yuan;

6. When the oil price dropped from 83.2 yuan to 80 yuan, the drop was less than 4%, and the oil price remained unchanged;

7. When the oil price rose from 80 yuan to 83.2 yuan, the increase reached 4%, and the oil price rose from 6.9 yuan to 7.2 yuan;

8. When the oil price dropped from 83.2 yuan to 80 yuan, the drop was less than 4%, and the oil price remained unchanged;

9. When the oil price rose from 80 yuan to 83.2 yuan, the increase reached 4%, and the oil price rose from 7.2 yuan to 7.5 yuan.
