I’ve been training in a cave, what are people’s unofficial speed card times who frequent sites like this? What’s the average? Are there alot of sub 20 second humans for speed cards, unofficially, here?
Check Memory League and look at the cards tab.
If you click on the names of people it brings up their top 5 times and you can get a sense of the ranges of the very elite. Lots of times around 15-20 seconds for the world-championship level folks.
It feels like there is a milestone time of under one minute that a lot of people make a goal of and can hit. Then sub-30 is the next tier of elite level which requires a lot of dedication. Then that 15-20 range is champion pro contenders, with sub-15 being the hyper-elite for cards (and numbers).
