A 4-Digit System for Memorizing Numbers
A few days ago, I wrote a post about a comparison I did of different memory systems when I was deciding on which memory system to use. I went with the 3-digit Ben System for a few different reasons. For decimal digits, having 1,000 images seemed like a good balance between compressing data and manageability. A 4-digit system with 10,000 images would compress more digits into each locus but seems like it would be difficult to develop and use in practice.
If people manage to make a 10,000 image system work, it could make things much more competitive. I hope they are successful because it would be great to know that it is possible.
Update: here’s a chart showing that 300 decimal digits can be stored in 25 loci with a 4-digit system compared to 225 with a 3-digit system:
