While playing on my SNES, I almost yanked my controller out of my console due to the cable being so short. I went on Amazon to buy a cable extender, and then started reading on different forums that increasing the length of your controller's cable can introduce a small amount of input lag.
Can this lag (in milliseconds) be modeled as a function of cable length (in meters)? If I have a cable that is x meters long, can I predict with reasonable suspicion that the input lag will be y milliseconds? If so, what is this equation/relationship?
