Graham 1.5T/C & 2.0T/C Tonearm - bias weight calibration notches corresponding values?

Setting up my Graham arm after a major move and can't remember the bias notches corresponding values . Graham didn't respond to my email. Are they .75, 1.0, 1.25, 1.50, etc.?
From memory...each indent represents 0.50 grams.
Thanks so much
It starts from 1.0g.  Each indent is 0.5g.  You can find owner's manuals at
Great thanks so much, should have thought of Vinyl Engine.
