Okey dokey so then if I am correct that a 2% solution drop equals 2.5 mg iodine then the 4% solution will be 5 mg.

My guess is the herbalist guy on YouTube who was giving the recipe for a quart was aiminng for a 5% solution since he metioned a quart of water and not 1000ml which is what I used. I went and used 1000ml which is more than a quart so it worked out to 4% instead of 5% which as I understand is the more "common" percentage for Lugols.
