So... really obvious question.

This sensor has three touchpads. You put your thumbs on the upper two and press the lower one (under the device) on bare skin on your knee or ankle.

Now, I'm not a mathematician, but that's 2+1 contact points which would be THREE leads not six.

There's a reason they put six (or twelve) leads on a ECG and why they put them where they do (mainly on the chest, but also on the ankles and upper arm)... to collect multiple specific signals.

So how does this replace that? I've gone to their website and cannot find any meaningful explanation.
