You don’t need the power in this test - at least not unless they make smaller increments than they do now. Because you can put an option in your layout that will show lights for every 10%. It also shows 1 blinking light at 5%. So it is the same as that test but much quicker. But the test will still be needed if you want to know how many characters you typed on the TB since the last charge. To me that isn’t a big deal outside of testing.
