I'm weaker than porkynator and Jakube
I really didn't do more than 10 attempts in my life and I'm wasting too much time on naming cards but it was really funny.
2:21 after 10 attempts is really great! I couldn't even break 4 minutes after 10 attempts.
My PB is 1:08 (after about 40 attempts). So: go, guys!
If you want to get rid of your "naming cards" delays, you should try running through a deck without memorizing. I did this a lot (> 100 times) and it was very helpful.
