It doesn't seem to work with hotkeyed spells (in that "test" appears instead of the countdown bar). Also, even when /cast is used, the countdown doesn't seem to be noticeably different between wands with different casting speeds. I took a video of me casting Icestorm with both my fastest wand (Valentines Day Wand - Casting time of 1.649999976) and my slowest (Zormite Wand - Casting time of 2.799999952) and both spells took 28 video frames to cast (including the countdown bar), with the countdown bar lasting 10 frames in both cases.
