You would double your review time. To cycle through the full 2704 images while practicing, would take longer.
I’m using a block hybrid, see here: 2018 2Card and 3 Digit System
I tried to make a system that I could reverse engineer for when I have a brain fart. I have 1000 locations and mostly based on the major system. I have all possible two card combinations and 0-999, I have not integrated binary. The complication is only in reverse engineering when I cant remember. My systems(borrowed from the Shadow System etc) is slower than the full 2704 ie staying at a loci if its red, moving on if its black. I decided, for myself, the cost of this extra step was worth the extra practice time I gained.
I am curious of what others have discovered?
