Yeah it is not a fast tire. Serves a purpose though.

For me, the more interesting bit is the relationship between pressure and rolling resistance. I used to keep mine at 40 psi (too lazy to pump at 50+
. I've ordered an electric pump
You might want to rethink that idea. As mentioned before, drum tests only paint you half the picture. On a drum the rolling resistance will continue to reduce as pressure increases. In the real world though once the tire has a bike and rider there is a break point. When you reach high enough of a pressure the rolling resistance will begin increasing rapidly. As in it's better to be severely under pressured rather than even a little bit over pressured.
