Nats,
Before you get too heated I suggset you accept that WK was talking 330/340 and, in that case at least, he is absolutely correct according to 1.27.50 p5... and I hope you are joking about the rest of your post or limit yourself to flightsim...
Overweight landing in an A320 is no big deal - and you are within your MTOW for your recent T/O so a G/A. overweight. is not going to present any significant problem
