Well, there's a lot of confounding factors that will throw your accuracy off with calculating how much CYA you've got in the pool. That's why testing is the best way of determinining how much you've got in there. Over time, due to drag out, splash out and pump out, your calculated number will diverge from the actual. It may be good for a short while, but eventually it will get off. Actual testing is really the best way to go about this.
