Russ Wilcox was seething as the referee failed to spot Dean Morgan picking up the ball in the build up to the Wycombe leveller, which arrived nearly a minute after the six allocated minutes of added time.
Ainsworth felt his side deserved a point on the balance of play, but believes his side capitalised on a huge slice of luck.
"Russ Wilcox will feel hard done by but we chucked everything forward and managed to get the equaliser", Ainsworth said.
"I have been there with timings of goals and handballs. If you look back to the Accrington game I think you'll see the biggest handball and the equaliser after that. You take the good and the bad.
"I didn't see it at the time but my assistant Dobbo said, 'Yeah, handball'. We might have got one back there. It's not nice with the opposition manager but you've got to take them sometimes.
"We've had things against us".
