Clark watched his side enjoy the better of the first half, despite going into the interval behind due to Marlon King's own goal, although Wolves were the more dominant force after the break.
Clark admitted he would rather be celebrating a positive result than a good performance, with defeat meaning Blues are still chasing their first back-to-back wins of the campaign.
And he feels the game was a missed opportunity as his struggling side, 19th in the table, strive to close the the nine-point gap between themselves and the play-off places.
"Results (elsewhere) gave us an opportunity, the top six hadn't moved any further away from us before kick-off. We could have actually moved closer to them," Clark said.
"I made a point of saying that to the players, a win would have taken us six points off.
"I spoke pre-match about chipping away at those nine points and the teams ahead of us and trying to cut that gap come January.
"Unfortunately we've just stood still, really. I'm disappointed with that and it's forced hand in hand with the inconsistency at the moment."
