Depends on how often you get the 'beep' I guess.
There is a beep when you have crossed the DRS line indicating that DRS is available to you. So you can open your rear wing. This would could happen once or sometimes twice per lap, depending on whether you are within 1 second of the car in front at the previous DRS sensing line. Some tracks have 2 DRS zones
Or .........
If simulated in this game for some teams (not sure if it is. and I've not tried Torro Rosso), it's a gear change beep, telling your to go up a gear.
In the real world some (or all?) teams get a beep in the headphones, telling them the best time to change up. Sometimes you used to hear the engineers on team radio saying something like "Sebastian follow the beeps", if the driver has not been changing gear at the ideal revs.
