Eek was my first impression of the requirements as well. It's a long test. It is usually given over 2 days. 1 day for Aikido (and randori), 1 for weapons. Once you have the skills it really becomes somewhat of a physical requirement for the Aikido - a mental test with all the weapons.
It is also the current requirements for Nidan. Obviously the techniques are expected to be more fluid/polished.
