Here here! This is an important lesson for us to learn though, as many of our users will probably have similar experiences. It's hard with small leaves to really know if you're completely covering the light guide or not... and honestly for all we know they are covering it but there's enough leakage if it's a tight fit that's causing problems.

I want to note also though that not only is the r2 a whopping .93 but the slope is 0.9... which means we're actually pretty spot on.

Is this over multiple devices, or just one device? I'm curious to begin seeing device / device variation as I imagine it's not insignificant.

Oh, also I wanted to note that this was using only a single device. I'm sure if we add more devices our variation goes up, though I'm curious to see how much.

Let's make a new Project and focus on device to device variation over different crops (now that the skinny leaf issues is addressed and folks are better trained). The outcomes would be:

1) How much variation in the r2, m and b values in the correlation are there between MultispeQ devices to a single SPAD device?

2) Does total variation or variation by device change over different plant types?

This is a good first step for Eric early this week, actually, you maybe just pass it off to Veronica or Ryan. Whoever does it let's make sure to link to it in the discussion section here.
