Adrian Jarvis became Bristol's record points scorer on Saturday but admits the squad are frustrated with their early-season form in the Championship.
The 31-year-old kicked his 709th point in the 26-21 win over Ealing to overtake Jason Strange (706).
"Jason Strange is a fantastic kicker and to have gone past him is great," Jarvis told BBC Radio Bristol.
"It's very frustrating and we need to sort it out. We cannot keep going with a lack of accuracy and concentration."
Bristol lost their opening game of the campaign against Bedford Blues, but have won their next five and sit a point behind leaders Yorkshire Carnegie.
They take on Yorkshire at Ashton Gate on Sunday and Jarvis said he hoped things would click into place.
"We are a very good team and we are just not showing it at the moment, but we will get there," he added.
"We will look at that and feel fairly disappointed."
