It increases my speed by 4mph as long as I increase my gears up one and keep the same cadence I normally do. Pretty much the same exercise, just faster. Works better when running errands on the bike as I get more done more quickly. I've 9 levels of PAS and can go up to 28mph but frankly I'm just fine around 14/15mph. No need to go faster even when running my errands, range matters more than speed with a lot of errands to do.
