Typing Weakness Analyzer

In short A words-per-minute score tells you that you are slow. It cannot tell you where, and that is the entire reason this exists. This times the gap between every consecutive keystroke and compares each letter PAIR against your own median, so what comes back is a list like "er is 40% slower than your average, ct is 60% slower" — specific, measurable and fixable. Almost everyone finds two or three pairs doing most of the damage, usually awkward same-finger sequences or reaches that break the rhythm of the hand. Pairs are the right unit rather than single keys because typing speed is not about how fast you hit a key, it is about the transition between keys: the same letter is fast after one neighbour and slow after another, and averaging per key hides that completely. Gaps over 1.5 seconds are discarded, because those are pauses for thought rather than motor delays, and including them would bury the signal. The output is a drill built from your own worst pairs, which is the part that actually raises a score — general practice improves what you are already good at, and targeted practice fixes what you are not.
