The Quins director, whose side were in front from the opening stages, watched the league leaders lose their grip on the game with 10 minutes to go after allowing the visitors to twice come back from large deficits.
"It's going to be good for us," he told Sky Sports News. "We're learning the whole time. We'll learn a lot from this.
"It was a horrific four minutes just before half time, and we just didn't get out of our corner when we had that seven-point lead. We had opportunities to get out, but we didn't.
"Leicester are a magnificent team. It was a cracking game. Both sides wanted the ball in hand, both sides were being ambitious."
Quins travel to Sale for the final game of the regular season in two weeks' time.
