Generally for fcing a map you need to "know" every part of it and sort of know what type of patterns you are going to encounter, unless the map is too easy for you to FC, that´s why golden says that playing the whole map, although it takes longer than restarting inmediatly (even if you failed), will later make it faster since when you pass the points you failed before you will be more accustomed to the map and probably fc it faster. That´s why SD sucks, plus its annoying because you do not control the restarts and that just gets on my nerves, sometimes when i fail i wanna restart inmediatly and sometimes not, plus it doesn´t add anything to the score so why bother.
