Rovers gave their chances of survival a huge shot in the arm, coming from behind to win 2-1 at Fulham thanks to second-half goals from El-Hadji Diouf and Jason Roberts.
The victory pulled Allardyce's side out of the bottom three and their 30-point total is ten short of that needed to stay up, according to the Blackburn boss.
With no other Premier League games this week, Rovers were able to see full value for the three points as they have clambered up to 15th place, much to the delight of their manager.
He told Sky Sports: "It shows what a difference it makes when we're playing a catch-up game and that makes the three points even more important and, of course, it drags a lot more teams - tenth, ninth, eighth - closer to us.
"It's three more points towards the survival total and that's looking like 40 to me - so 10 points to go."
MassiveRovers trailed to a first-minute Clint Dempsey goal but came storming back at Craven Cottage and Allardyce was delighted with the fighting spirit shown by his team.
"It was a massive victory and I think a well-deserved one. It's not just the victory; it's the manner of the win," he added.
"The way we started the game and gave Fulham a goal in such a sloppy fashion made life extremely difficult for us but we fought our way back and showed some great quality with our finishing in the end."
The vital finish came from striker Roberts, and Allardyce was full of praise for his frontman's goal.
"The strength and power of Jason Roberts paid off. He showed his strength, made a great turn and a good finish. I thought it was what we deserved today."
Roberts was also thrilled to play a crucial part in such a vital win.
"We are ready for the fight to stay in this division," he said.
"We asked ourselves some questions and came up with the answers. It was great to get the three points, especially away from home and we are feeling very, very good about it.
"We don't want to be in that bottom three at any time. None of us wants to be part of a Blackburn Rovers team that gets relegated."
