\DeclarePeriodicCounter{section}{10}

\newcounter{foocntr}

\begin{document}


\setcounter{foocntr}{3}% 
\AddPeriodicCounter{foocntr}{8}% 

Value of foocntr is: \thefoocntr  % Should be 3

\addtocounter{foocntr}{20} % Is it 23? No, it is 23 % 8 = 7
Value of foocntr is \thefoocntr\ now! 

Adding a value of 4 again: 
\addtocounter{foocntr}{4} % Is it 11? No, it is 11 % 8 = 3
Value of foocntr is \thefoocntr\ now! 

Now prevent the wrapping
\addtocounter{foocntr}{10}[wrap=false] % Is it 13? No, it is 11 % 8 = 3
Value of foocntr is \thefoocntr\ now! 



\foreach \x in {1,...,22} {%
  \section{My nice section \x}
}


\clearpage

\ChangePeriodicCounterCondition[reset=false]{section}{5}%

\foreach \x in {1,...,22} {%
  \section{My nice section \x}
}
\clearpage

\ChangePeriodicCounterCondition{section}{7}%

\foreach \x in {1,...,22} {%
  \section{My nice section \x}

\clearpage

Now removing all periodic counters, but don't reset them
\RemoveAllPeriodicCounters[reset=false]%

\foreach \x in {1,...,22} {%
  \section{Section after removing  periodic counters \x}
