Note: During a conversation with Christopher Rice (the author of that article) on the GURPS discord, he noted that he'd probably be more inclined towards the -80% version these days. So either -50% or -80%, depending on which source you consider 'more' primary/relevant.

Thanks!

I might treat One Person Only similarly if the One Person is an attached Always Available Ally (one who's just around as often as other PC's should use the normal -80%).

If a GM opted to go with -80%, however, I wouldn't object.

I went through this thought process pretty much verbatim after reading the first reply!
