INSIGHT: How often does the team that tops testing win the Constructors’ title?

Every year the F1 teams gather for at least one pre-season test where they try out their new cars for the first time and try to iron out any problems before the first race of the season.

Of course, no one outside each team really knows what run plan is being used, what parts are being run, how much fuel is onboard and how far the power unit is turned up, so predicting the competitive order from the testing time sheets is difficult.
