The code looks likes this, but this examples does not exhibit the same
faulty off-by-1-page interactive page jump behaviour. In the chapters in
the body matter, always directly after a new chapter a section begins (in
this example omitted).

\setupinteraction[state=start]
\setuppagenumbering[location=,alternative=doublesided]
\definemakeup
  [titlepage]
  [align=middle,style=\bf]
\starttext
\startfrontmatter
Small title
\page
\phantom{x}\vfill
Colofon
\page
\starttitlepagemakeup
BIG TITLE
\stoptitlepagemakeup % <- empty page inserted after here, so page number
becomes 5
\setcounter[userpage][5] % <- without this, the page number = 3
\setuppagenumbering[location={footer,middle}]
\completecontent
\chapter{Introduction} \dorecurse{4}{\input zapf}
\stopfrontmatter
\startbodymatter
\setuppagenumbering[location={header,middle}]
\dorecurse{21}{\chapter{Knuth} \dorecurse{10}{\input knuth}}
\stopbodymatter
\startappendices
\chapter{Appendix} \dorecurse{4}{\input zapf}
\stopappendices
\startbackmatter
\chapter{Notes} \dorecurse{4}{\input zapf}
\stopbackmatter
\stoptext

I'ĺl start trying \enabletrackers...
