The Whites are currently in the bottom half of the Championship table.
Despite beating Birmingham City on Tuesday night, Steve Evans' men are 15th in the table, 17 points adrift of the play-off places and in fact, slightly closer to the bottom three.
And while the performance against the Blues was incredibly encouraging, Dallas admitted that being able to back up positive displays with points, and then do it on a regular basis has been the team's problem this year.
"There's a lot of you can look at but at the end of the day it comes down to the fact that we haven't performed well enough on a consistent basis," he told the Yorkshire Evening Post.
"We've shown that when we come up against teams at the top of the table, we're able to perform against them. We just haven't done it enough. We've dropped too many points, from winning positions or going from getting a point to not getting nothing. It affects you but you have to pick yourself up and go again."
As well as the result against Gary Rowett's men, the last five games have arguably summed up the issue that Dallas has been talking about.
While they were able to beat a team that has spent much of the campaign chasing the top six, and put in an excellent display against league leaders Burnley last weekend - where a sluggish start and then an inability to take their chances saw them fall to a narrow defeat - they are also capable of shooting themselves in the foot.
Against Huddersfield last month, they capitulated to lose 4-1 despite taking the lead, and it was another defensive error that led to them losing against Rotherham in the first game following the international break.
And while most of the pressure being off could result in Leeds managing to put in some more encouraging performances before the end of the season, it will be during the next campaign that Evans will want to see the team consistently beating the sides below them while also putting up a good fight against those battling near the top.
