G'day Guys... 
The notches and numbers on a grinder's adjustment dial are not an absolute reference, but a relative one. Not really practical to try and emulate the performance of your grinder with that of another by using the same 'numbers' or 'notches'...
It's nothing more than a fluke if it happens to work out....
