The Mexican has failed to feature in Q3 on six occasions this season, making the cut just four times.
This includes an ongoing streak of five early exits, a run that has seen team-mate Max Verstappen take pole position on each occasion.
Although Perez has recovered positions during the races, he has only been able to reach the top three by the chequered flag once during this period.
Asked if he has been overdriving recently, Perez conceded: "Yeah. Certainly, when you're not fully confident with the car. I think what happened in Monaco probably brought me a step back and it has taken me some time to fully trust the car the way I was doing it.
“And then you add the external factor from the changeable conditions. And then there is a bit more of a discrepancy."
In a bid to get to the bottom of his qualifying struggles, Perez spent time at Red Bull’s Milton Keynes base last week.
