tumbler, and everyone -- thanks so much for sharing all this stuff.  I just can't post much lately and can't do much in the evenings, but want to really thank you. 

tj6p -- your post, too, thanks very much.  Also, I want to say, this is much the way peter Campbell trades his systems.  As the system scales in, the added positions are larger.  If the scale-ins work at all, which the obviously do, it really makes sense.
