Yeah, it's pretty silly that they don't have clear documentation on some of their commands. For /wait, though, a number of people have actually spent the time testing the values you can input (mostly for crafting macros), and the .5s all round up to the next closest whole number.

Since the .5 is still adding a full second to the wait timer, anything that needs that extra second to activate will work with the .5. If you put .4, though, it'll probably break again, since that rounds down instead of up.
