Well, if I do implement them then I am going to expose all constants in a settings file so that people can keep them updated even if I get schmeared by a bus and can no longer mayk teyp gud. There's also no way for me to know whether it's broken or not, other than people reporting that it doesn't work. What I can do is initialize the variables to innocuous values, so that they will just stay stuck at zero (or whatever) if it doesn't work. Regardless, this will likely be a problem for the weekend rather than the week.
