You never know when tex will break a page unless you are explicit so

The rightpage check combined with putting a signal at the spot where
you test will work ok.
The odd/even test works as expected when you're in the page builder
(wrapping up the page).
Is this also the right approach to check for the current page within a
float placement?
Like
\startplacefigure[]
\dontleavehmode\signalrightpage % necessary?
\doifelserightpage{RIGHT}{LEFT}
\doifelseoddpage {ODD }{EVEN}
\stopplacefigure
?
In my macros from 2015 I’m still using manual right/left page versions,
and I’d like to enhance them.
I need e.g. different \offset values for \externalfigure depending on
right/left page.
normally you will use "inner*" and "outer*" placement there as in other
cases (which uses the same tricks)
