Received my TF Test Kit yesterday and tried it out tonight. Nice kit.
One thing I would suggest. On the chart, it would be nice to at least have the ideal ranges listed next to each row header.
I use the downloaded one from your site and edited it to add those. Then I also added other useful info/charts to the bottom, ie the chart for what your chlorine levels should be based on your CYA and what chlorine level to shock with.
