"WPM" is the standardized measurement, albeit imperfect and less reliable compared to CPM/APM as a measurement via a pure totality. There's also a reason that nearly every other site has integrated the option to record by CPM/APM as opposed to only WPM. It's actually more odd how much virtually archaic questions are still being asked.
Also, stop acting like a bitch in Multiplayer and quitting at the first sight of being overtaken in a race, it's flat-out pathetic if you're someone actually attempting to achieve improvement. You've been submitting the same results for years now, it's sad really.
