In this chart found [here](https://dev.blues.io/notecard/notecard-walkthrough/low-bandwidth-design/), can someone explain what this chart means in terms of data usage? If I were to use a compact format templated Notefile, which column(s) should I look at? I’m not sure if I’m supposed to just look at the Compact column or if I’m supposed to do something like Data minus Compact.

If you’re using `"format":"compact"` you would look at the Compact column only. We can look into renaming the Data column to make this a little less confusing.

Thanks,
