I only add 1 qt of 10% (or 1.5 - 2 qt 6%) each evening (for now anyway). I have my 2-qt plastic pitcher marked for each half-quart with a black marker. I pour bleach to the 1st half-quart mark, fill the rest with pool water and slowly add it to the skimmer. Then repeat that process to reach my 1 qt of 10%. Which means, it takes me about two minutes to pour bleach, dilute with pool water, pour slowly into skimmer... and I'm done!
I guess it would depend on how much bleach you have to add each evening. But even at three or four quarts, it would still be quick and easy to dilute each half-quart with pool water in a 2-qt pitcher and add it to the skimmer.
