You probably have a little more forgiveness but not day and nights. I did my own real world teasing on my 23L barrels and was shocked when I saw the numbers. Guess I shouldn't have been since they have such a high ratio of wood (area) to wine. I would still guess you would be down to basically bill in that 100L in 4-6 months tops without any extra addition. Thats another ~20 grams needed over 4-6 months (after your first full addition) which works out to a LOT more than 1/4 tsp every 3 mo!
