The take away point not made yet is to make checking the slack in that cable when you're done hooking it all up a key part of that check list!
If the cable's length is set for the pedals being "back" all the way, and you happen to have them forward without thinking about it, you'll have noticably more slack than normal. Hopefully, that will jar the brain into gear when you notice that?
