Decided to do some calibration in that area. The last print I did including all supports came in at 172g.
Easy calibration, I set the g/cm3 lower and resliced until I got that number or very close to it. Out of the box the profile is 1.25g/cm3 and I ended up with more like 1.03g/cm3.
The larger the print the more accurate this will be but any print over 40-50 grams should get you pretty close.
