Hey, thanks for playing. A hint for the 2.5g: You can pour stuff from one cup to another.
Yeah I did that and got the scale to what I thought was 2.5g compared to the 5g weight so not sure what the issue was.
Oh, yeah. We did not realize when drawing the scale that it might confusing. But the tick marks on the bottom of the scale don't mean much in terms of actual weight. It's the balance that matters
