Dear gene,
Correct me if I am wrong, but do I have to look for articles that sustain your arguments, while I object to them? Maybe it works like that in the upsidedown world, not here.
If you make a statement and support it with an reference than I will check the reference. If the reference doesn't cover your claims I will let you know. That's what I did.
And you say:
"By the way, I stand corrected, the L excess is between a lousy 2 to 9%"
That's not exacly what we need, isn't it?
Best wishes.
