Again, do you want me to send some boards? At your cost if you are wrong.
What sort of machines are you running? I assume both a buzzer and thicknesser. Which makes we wonder why you are saying 11mm. From my experience - and it follows industry standards - a rough sawn 25mm board comes down to 19mm when dressed.
That's not a deviation of 1mm.
Perhaps you can educate us all.
