Despite of the average possitons gained or lost, and considering a deeper analysis of the performance of each strategy, we consider the 2 stops strategy as the optimal for this race.

It is important to note that this might not always be the case for other races held at the Sepang International Circuit, as the conditions might change from year to year, in terms of wheel degradation, accidents, safety cars, etc.

The conditions of the track got worse between the two sessions of the qualifying, and only 1 driver was able to improve his Q1 times.

The Q3 is the time were all the remaining drivers put all their cards on the table, even those with a superior car who might have been managing their times in Q1 and Q2 push their cars to the limit in Q3. However, the conditions of the track worsened from Q2 to Q3, and none of the drivers were able to improve their Q2 times.
