Final rankings use this application's selected tie-break order; Lim itself does not prescribe it.

About

  
Experimental implementation of FIDE C.04.4.3 Lim, effective 1 February 2026.
     NOT FIDE-endorsed.

  
Implements ordinary, non-Maxi pairing, the two-sided scoregroup traversal,
     compatible-opponent checks, floater selection, median-group repair,
     colour preferences and the last-round same-score exception.
     Complex cases can have more than one interpretation; this is not an official checker.

  
Does not implement late entries,
   acceleration, or adjournments. The actual colours of a game in the latest
   archived round can be corrected before generating the next round; other
   archived results cannot be edited directly. To change a previously reported result, a backup of the round must be loaded and the round results re-entered.
 

This non-Maxi implementation does not minimise or cap the rating difference between opponents.
     The program has a built-in fixed search limit.
     Failure or interruption never publishes a partial round.
