because not all mods are perfect, and you may be proficient at timing on certain bpm/njs, but not others. for many, a longer notejumpspeed will cause them to miss, as they misread the visual timing. there is also the decent chance that you are actually mis-swinging the direction, but without any clip or context, it's impossible to say. you say you have the replay, why not record that?
how is top players noticing it immediately retarded? they are the players who not only definitely play more than you, but would notice it first, and report it first, because they're the ones who are competing at the highest level.
