Yes, and looking at the geometry figures for other bikes, it doesn't seem to make sense.
Did you use a spirit levels to ensure the distance from centre of bottom bracket to centre of headtube is correct?
Also, if the bike is leaning against the wall, it can throw it off slightly, and lastly, an uneven surface can throw it off noticably.
Found the original geometry chart, not much info to create a virtual stack and reach unfortunately;
Seat tube; 48cm Top tube; 54,50cm Seat tube angle; 74° 30’ Head tube length; 147mm Chainstay length; 405mm Head tube angle;71° 30’
I did find the Wilier a little long, but can't be 425mm long!
