I started this post to clarify that my comment about the thickness and separating into layers of single mix RA dev repl concentrate was about other brands. I suspect Kodak approached it the same way, but it would be worth checking. I'm not sure but think it was Fuji and Trebla (or Champion) my experience was with.
Now I also see that I may have misunderstood your original post. I thought you were mixing partial quantities from the mix bottles, but as I read it again it sounds like you are mixing the full bottle, then storing the mixed solution in multiple smaller bottles. The issue I spoke of in mixing partial amounts wouldn't be an issue in that situation.
No - you read it right - I mix partial quantities.
