I use an analog/mechanical(?) scale in oz, estimate and convert. But 1 oz = 28 grams so it's easy to be off by a lot. I went to Fry's just now with my DA, IME 3.0 and WMO and put them all on a digital scale multiple times. Results I got were roughly 80g 95g and 110g for the WMO, IME and DA 3.5G.
So yes your original data is more accurate. I changed it back. It's gonna be interesting though when someone sees my measurement for the DA3.5G at 110, and the measurement for the DA3G at 133, lol.
