Hey, I was just trying to keep it anonymous so my friends in the solder
paste biz do not worry to much.  Thanks for being so detailed and thorough.
.......wise guy's ;-)

Just to emphasize again. The flux is being removed 100%. Verified by
removing a part right after the wash and rinsing w/IPA. The solder joints
look ok no residue!

George points out:

95Pb/5Sn/2.5Ag adds up to 102.5%

Doug points out:

102.5% can lead to excessive solder joints, or the flux manufacturers have
found a way to manufacture a -2.5% solids flux........
