The Tykes are three points above the relegation zone with one match remaining and travel to Plymouth on Sunday knowing a point will ensure their survival.
"It could've been different this year. There's lots of games where we've competed and just fallen short with a mistake or a decision," Davey told The Star.
"In four of the last five games we've conceded a goal in the last three minutes which has meant we've drawn a game. We would have been safe. There's bits and bobs throughout the season we can reflect on.
"At the end of the day we are where we are and we have to make sure we put everything right on Sunday."
