Re: Pointer target spacing issues

Thank you Patrick. Makes sense about BBC, added those in addition to the
most relevant ones just in case. Thank you for pointing that out.

The question is about 2.5.5 being AAA and 2.5.8 AA - should we discuss with
the group having an AA for target size, or would adding a reference to
2.5.5 to the 2.5.8 understanding document suffice?

I'll send a PR to add the reference either way and we can bring up having
an AA for target size with the group. Thank you!

Best,
Sukriti
