Actually, while you are hauling 100 gallons, you don't have access to all of it.
What you are doing makes sense, but you really only will have access to 95 gallons (and probably less because you can never completely empty your FW tank).
You won't get more than 95 gallons because that 5 (6?) gallons in your water heater and plumbing is never available to you. Once you are completely out of water, you will still have a water heater full of water. It only comes out of the hot water tank when there is water coming from your fw tank to push it out.
What you are doing is a good thing, because if you didn't do it, you would have access to even less water.
