Dover first team coach Mark Newson said attention to detail helped pave the way for Tuesday's impressive 3-1 home win over Woking.
The victory at Crabble extended Dover's unbeaten run in the National League to seven and took them back to the top for the third time this season.
All three goals came from set pieces - the first two from top scorer Ryan Bird, the other from defender Manny Parry just two minutes after had Joe Ward replied for Woking - and Newson revealed Whites felt it was a an area they could exploit.
He said: "To be honest we give ourselves a little bit of credit there, we did a bit of homework, we've had them watched, we knew there was a weakness in that area so to score three goals in that way has proved the case."
Newson said the management team were delighted with the performance as well as the win and he felt Parry's 56th minute goal - his second of the season - was decisive.
He added: "It was a good result really against a side who, apart from Saturday, have been getting some good results. We were pleased with the performance against quite a young but lively and exciting side.
"I'm pleased for Ryan and for Manny. He's been terrific the last five or six games and has been the most consistent defender so I'm pleased he scored as well as Ryan.
"We showed great character to come back like that but we've got that within our side. As the season's gone on, when we've gone behind we come back and shown some resilience.
"I'm pleased that we did score so soon (after Ward's goal), if we hadn't we might have been in trouble a little bit so we're pleased with that."
On the two previous occasions Whites have gone top they've immediately surrendered the position but Newson hopes Chris Kinnear's side can sustain their challenge a bit longer this time as they prepare to head to Gateshead on Saturday.
He said: "As the season has gone on, looking at some of the results, playing some of the teams we've got just as a good a chance as anyone else (of being up there).
"Gateshead got a good result tonight against Leyton Orient (they won 2-0 at Brisbane Road) but every time we've gone up there we've had a good result over the years and we expect that this weekend as well."
