So it is by weight, not some other form of "baseline" so my statement stands and is not a non sequitur. That's all you had to say, just admit that you were incorrect.
report contains results of quarterly sampling as well as extremes and averages from 1995 until the present. This was the most recent report I could easily find archived.

The linked report will give you the gist, percentages are in % by weight
