As the title says, I’m curious what the minimum memorization proficiency is for competitions. What times would correspond to a decent placement at a competition? I did some searches, but I couldn’t find anything on the topic.
Also, as I understand it, there are ten categories. Do all entrants have to partake in all categories? Would it be possible to only compete in select categories, like speed cards and numbers?
Lastly, does anybody have a recommendation for a good book that encompasses all categories in a competition? I currently only practice decimals, binary, and cards, but I have an idea of how the general concepts might apply to other categories.
