So the good news is, waits do indeed now work correctly. But something still isn't right with the execution. Tried this simple piston (turn light on, wait 4 sec, turn light off):

As I recall CoRE had an option to turn off command optimization but I can't seem to find a setting to do that in WebCoRE.
