TeX commands such as \userpagenumber "gobble" a trailing blank space, delimiting the end of the token name ("userpagenumber"). It can also be terminated by any non-token-name character or another token. So we generally write \userpagenumber\ . One could also write {\userpagenumber}, i.e. enclosing the TeX command within delimiters, and it is a question of taste what coding is more readable. \userpagenumber{} is also valid, yet I find this even less readable.
You can learn much from emulation, paying attention to details, as Wolfgang had written
\setupheadertexts
[] [Page \userpagenumber\ of \lastuserpagenumber]
[Page \userpagenumber\ of \lastuserpagenumber] []
One tricky point that might not be obvious, \setupheadertexts can take a varying number of arguments enclosed in []. The form above (4 groups of []), sets the left/right headertexts for even/odd pages. Whereas the single group instance
\setupheadertexts [My Spreadsheet]
sets the center text. Having three or five group versions gets unwieldy or ambiguous (the two group version sets left/right for singlesided layout), so having to make two "calls" to \setupheadertexts as above is cleaner, although was confusing to me at first.
