A credible producer of quality pop ups said to me that it should only be used in a winter bait or pop - up(he used it in all his pop-ups),it's not a flavour or attractor but allows the bait to release it's properties at low water temps(due to it being a carbon acid ?), 1-2 drops per egg.
Why don't you try 2 pop-up mixes,one with and one without,bung it to 2 mates on the same winter water and don't tell them who has the Nba pop ups..there may be a trend.
1 Egg
5-10 ml ea flavour.
2ml clear sweetner.
level teaspoon betaine.
1-2 drops Nba.
Colour of your choice.
Richworth pop up mix.
