If Galak (considered a reliable reference by my counterparts

Here is my approach :
I just drew the circles of the different ranges.
On the original BB field, the squares are not square :
Lengh : 2,8846153846153846153846153846154 mm
Width : 2,9 mm
I chose the shorter one : 2,884... mm side.
Is this template for Passes correct ?
