I think this makes more sense if only a small portion of all files from the laptop complete the ENTIRE loop. if the total percentage of files which complete the entire loop is 0.0004% , and he backups once a month, that should give him exponential growth slightly smaller than Moore's Law. At 18 months, his total file size would be about 168% of the original. 220.127.116.11 22:03, 10 August 2016 (UTC)
Also, the title text my refer to that often when you lose a project and have to start over from scratch, the project become so much better.
