Back to this topic again. Is weighing reliable? I've heard concerns about counting out the right number of pieces for the job before beginning - another one of those "too operator dependent" complaints, so I like the idea of weight as an unbiased measurement. But is the weight of the b-stage tight enough to allow for weighing to be an acceptible counting method?
