Those numbers/amounts are based on the rating plate information only. It takes a true watt meter to know exactly how much power you are using, but these types of estimates are usually very good, if maybe on the high side.
If it makes economic sense to you to go with the Waterway, that is a good choice. You would, eventually, make up the difference in energy cost with a VSP, but that depends on how you use your pool system and the cost of power. It could take years.
