No, the map gets updated or just filled up whenever time blinks out from down under the sofa and gets caught. No other system to that.
But I only change/add links whenever I put in something 'new' like forks, comments or whatever there is noteworthy. If there's nothing to report I only fill up the COMP data without changing the filename.
I can see from the msgs I get that a map update is wanted by many and you can be sure that I'll get down on my knees to catch time in it's hiding as soon as there will be need for that.
