It is a bit disappointing to see you bring this up again after it appears we had reached agreement that HG/HG+ is not equivalent to PG.

The Hoagies page we've been referring to does not actually mention percentiles, rather summarizes the approximate equivalent test scores. These are overall test scores, Full Scale IQs, not individual subtests nor GAIs. As you now mention "HG/HG+ as 99.9th percentile (per some definitions, like Hoagies)", can you point me to the definition on Hoagies which you are referring to, which defines HG/HG+ as 99.9th percentile?

That may depend upon the context. One may choose to ask for clarification.

In the context of a thread specifically about giftedness and level of gifted (LOG), yes.

In other contexts, possibly not so much.
