“How many brush strokes a minute does it have? 62000 or 31000?”

1-2 of 2 Answers

• 1 brush STROKE (an up and down motion) = 2 brush MOVEMENTS (one up, one down) And that means … 31,000 brush-STROKES-per-minute = 62,000 brush-MOVEMENTS-per-minute. They describe the same rate of speed (frequency). So, there’s nothing new and improved here. Both brushing action descriptions are equivalents.
