There is a simple solution: don't limit the number of save files submitted. What difference does it make if they just sit there until needed? Only the last submitted one counts. I don't understand the organizers' position, especially that of the respected VDV_forever, who, although he wants to improve his result, can't do so because of the rule of only one save file. So the question is: will the winner really win, or will he just play better than his opponents in a rough draft playthrough?
If I have time, I will participate too. I looked at the map today and skimmed through it: it's quite tedious, to be honest.
