If you miss the mark, there is a restart right away, there is no way to understand you clicked sooner or later or you miss(miss the line). Why not make a black screen with the inscription "early" "late" "more precisely" "miss line" (or just show the value scale for a few seconds) before the restart. After all, then it became possible at least to memorize and correct. And so slowly moving around the map you will get your well-deserved SS.
