I timed myself walking from the starting block to about 30 feet from the starting block. I timed myself wandering around the
link stands. I timed how long I could hold my breath
link under the Oregonian sun (one minute, precisely). And I timed how long I could speed walk from the starting block to about 30 feet from the starting block. Riveting stuff, which is all to say that I found the user experience
link easy and accurate on the SRQ041.
