Tingling - issue with table in book?

Chapter 2 and chapter 7 of the HPL book clearly describe tingling (in the arms & hands) as a symptom of hyperventilation.
The revision tests for both these chapters include very specific questions linking tingling with hyperventilation.

However - the table at the bottom of page 69 (Condition/Symptoms/Treatment) shows tingling as a "main symptom" of Hypoxia. The entry for hyperventilation does not mention tingling.

Am I correct in thinking this table must be wrong?

I have checked the errata page and there's nothing since my book's revision date except the comments on REM sleep.

Be very wary of trying to push hypoxic symptoms into a neat box.

One of the reasons the military require chamber runs is to accustom folks to their own particular hypoxic symptoms. Some folk don't recognise anything much - I thought I was going great, didn't know I had passed out and knew nothing more until the flight surgeon got around to putting my mask back on.

Not everyone experiences the neat textbook story ... one of the reasons I am amazed that civil high flyers are not required to do at least one run to have a looksee at the problem as it might affect their particular physiology.

It's definitely a contradiction in the text. @stuart?
