How many journeys do competitors use for each Memory League event? Are ghost images from previous training sessions an issue?
I guess it depends on how often you train/compete each discipline. I would think that if you were going to practice each event five times/day, and you were using two images/locus, you’d need at least 75 loci for Images, 130 loci for cards (assuming a 1-card system), 100 loci for numbers (if you’re using a 2-digit system), and 125 loci for words (if you’re one of those fantastic athletes that can do all 50 words). Most athletes don’t use a memory palace for Names & Faces. This is all assuming your ghosts don’t hang around for more than 24 hours, but I’ve read that it does vary from person to person.
