Auto-sizing Symbols by Stops

[jenbell27]

In Smart Mapping, you can either specify a size range's min and max values for a point OR choose the "Adjust size range automatically" option.

The "Adjust size range automatically" option currently has 4 breakpoints which causes the symbol size changes to be pretty drastic and doesn't focus on the mid-scale ranges (or the "sweet spot") of the map and data.

To address this, Jim Herries used a function in Excel to suggest specific sizes for every scale that highlights the high values of interest as well as the mid-value variances while downplaying the lower values.

Here is an example of a map that has a specific min and max size for every scale.

And here is the JSON:
