Ever watched an formula one qualifying session? According to the rules, all drivers must drive a timed lap that's within 107% of the best lap in the Q1 session. If a driver cannot drive a timed lap within that limit, that driver isn't allowed to participate in the race.
That rule is easy enough to understand, but how easy is it to find out what 107% of the best time is?
The 107% Calculator app does all this for you! Just enter the best time using the picker wheels and you'll immediately see what the current maximum allowed time is. With this app at hand, you'll have no problems figuring out which drivers are on the safe side and which aren't!
