Skydream What I posted is from a very old document A319/A320/A321 Flight Deck and Systems Briefing for Pilots. All that I understood from your post is your company is having problem with short overspeed during retraction of flaps 1+F to zero. This can only happen at high takeoff weights. At 210kt the flap part auto retracts and during slat retraction a short overspeed sounds. According to Airbus that's not a problem but retraction to flap zero should not be delayed. You are adviced to read Safety First magazine control your speed during takeoff. It's a series on speed control during entire flight regime.
