 - #### Defining the type of axis and range values wisely
 As with the name definition, the axis' type of value should be reusable. It should both serve the particular needs or uses of the project submitting the axis and try to anticipate the possible ways it could be used for other projects (See [Type of axis](https://googlefonts.github.io/gf-guide/axis-registry.html#types-of-axis))

+  - Defining an axis as a Boolean might not be valid for further font project needs, as is happening now with Wonky axis.
   - Ranges that are overly narrow or too wide would leave either insufficient room for the inclusion of other steps or too much to create meaningless intermediate steps. As an example, YEAR axis original range was including only the period covered by the original project (1979-2050). The range was redefined to a broad scope that could support other projects using the axis (-4000 — 4000).
   - The following values must be included
     - **`min_value`** The lower bound of the axis. Inclusive.
     - **`max_value`** The upper bound of the axis. Inclusive. 
-    - **`default_value`** Default position of the aixs.
+    - **`default_value`** Default position of the axis.
         The default value should work as a reference. It is possible to override it in the family `METADATA.pb` file so that the axes keep their reusable purpose.

     - **`precision`** Describes the specificity at which an axis position can be specified.

 The default is usually always the same, e.g. 400 wght, 100 width, 0 mono. 
 For new expressive axes, the default range for these is likely to be a percent range 0..100, and probably with a 0 precision value (meaning no decimal places). The default might be 0, 50 or 100 depending on if the axis is adding something that usually isn't used, something that usually is used but can be turned up or down, or something usually used that can be removed. Width is unusual as a relative percent range, as it has 100 as default and goes up and down from there.

-Few binary axes have been registered as pseudo boolean behavior with off and on positions but with two or three decimal places allowing a range.

 This would allow for the user to choose things like the size or thickness of features like Old Style Figures or Small Caps. This approach would also reduce the file size as the data for these axes does not exist; they are composed of the combination of other axes. Roboto Flex is 1.8 Mb, but Roboto Flex with avar2 Is approximately 300 Kb, an 80% file size savings.

-Named positions are similar to, but different than, fallback positions. Fallback positions were originally defined for the legacy axes, width and weight, to cover the axis values that matched the pre-VF world. Google Fonts creates static instances at each of the fallback positions and delivers them when a requestor does not support VFs.  For example, when wght=451 is requested by a non-VF client, Google Fonts could deliver weight 500.
