Plymouth boss John Sheridan praised strike duo Reuben Reid and Marvin Morgan following his side's 1-0 win over Rochdale.
Morgan won the 25th-minute penalty which was converted by Reid and Argyle should have extended their lead but Conor Hourihane curled a shot off the crossbar.
Sheridan admitted: "It's always a good habit not to concede and end up winning the game, which is a plus point.
"It can only breed a bit of confidence into the players.
"I think everybody could see it was a game of two halves, but it should never have got to that.
"We played really well in the first half, on the front foot, caused them loads of problems and should have had the game sewn up by half-time.
"But with a team like Rochdale, who are very confident in the way they play and pass the ball, at 1-0 they believe they have got a chance and second half they came back into it to be fair to them.
"I thought we just took our foot off the pedal and I haven't got an answer for it. I tried to ask the players they didn't have an answer.
"I thought the front two caused them all sorts of problems and I told them to play off the front two.
"I was very pleased first half but now we have to turn that into a 90-minute performance."
Dale boss Keith Hill, a former Argyle central defender, said: "We conceded a very soft penalty caused by a catalogue of errors.
"We had three chances to clear it before it came the ball into the penalty area.
"We have been working on our strategies all week and when you go 1-0 down to what will be a very good home side like Plymouth, it's very difficult.
"I thought the first was relatively even. We had opportunities and so did they. It was too open for my liking.
"We had to dominate the ball in the first half like we did in the second and that was our strategy.
"We kept giving away the simple pass, the clinical must-complete pass and that caused our defenders all sorts of problems because Plymouth counter-attack well at home.
"I was relatively pleased with the second half but there is no solace in losing that game.
"We squandered opportunity after opportunity. To a certain degree the performance was more than acceptable and it was one-way traffic in our favour.
"We should have equalised because we should have made the most of one of the opportunities we had because we put the opposition under severe pressure. With the combination of some good defending and bad misses we failed to score."
