Thats still a wastefully heavy mix. Overkill if you figure with a 32oz bottle on the foam cannon, 30% soap... thats almost 10oz of soap per wash. You might as well light a couple of dollar bills on fire while your at it.
A good soap should be able to generate lather comparable to what I had in that video with 2-3oz... even going to 4-5oz tops.
In the grand scheme of things, it's not that much money.
