Hi Wayne,

Thank you very much for doing this research. Based on this new
information, do you still consider the spacing metrics in the Adapting
Text SC [1] adequate for when a large font-family is selected and/or
increased spacing is applied to text? It currently is:

* line spacing (leading) to at least 1.5
* letter spacing (tracking) to at least 0.12 em
* word spacing to at least 0.16 em

Do we need to increase it or is it still okay?

Thanks again.

Kindest Regards,
