The Darts went down to a Louis Soares penalty in Berkshire but remain top of the Vanarama National League South table on goal difference.
Saturday represented a missed opportunity for the Darts to keep some breathing room between themselves and the chasing pack.
However, boss Burman thought their performance at Bulpit Lane was better than the one at Poole Town a week prior - a game that netted them three points.
He told the Dartford website: “Once again it’s unfortunate that when we have started a match in a good position at the top of the table, we have managed to lose a game that in my opinion, we should have won.
“I think the players’ attitude throughout the game was excellent and although we gave away a penalty, other than that defensively we were sound.
“Going forward, we have created a number of chances in the first half and many more in the second half but unfortunately these chances were not converted into goals.
“We are all disappointed with the result but we are going to get disappointments during the season and it’s how we react to these situations especially over the coming few months.
“There is still a long way to go before anything is won or lost in the title race.”
