Swirling or stirring - what's the difference

[ubalr1]

With all the pool tests I've ever used, the goal is just to get it mixed. Maybe if you've got some sort of unusually test that depends on precipitation, it would matter whether you stirred instead of swirling. But I haven't seen anything like that with consumer (or even dealer) level pool testing.

Thanks. The only thing I can think of maybe is contamination (from a previous test, etc.) skewing the test in progress. My wife likes to use a little wooden stick to mix, and I prefer the swirl.
