After trying a few different ways to make Lipo-C,I settled on putting 3 tblspns 
of Soy Lecithin in one cup of DW and let it sit  at room temp.until Lecithin 
was fully in solution.Then I put two[2] tspns of Ascorbic acid in 1/2 cup of DW 
plus one tspn of bicarb [1],let it fizz right down.If I see any sedimentation 
on the bottom,then I tweak it by adding a pinch of Vit.C.,if it fizzes then I 
add a bit more until no reaction.If the first pinch of C does nothing,then I 
add a pinch of bicarb,if it fizzes then I repeat the process until no 
reaction.I have found this to give me as close to 100% as you can hope for.
In my last four brews I had two with very slight traces of Leci. floating on 
top.These seemed to be from larger sized granules.
When I measure the Lecithin I do notice that the size of the granules do 
vary.If I had a precise scale I would try doing it by weight, just to see.
