The trainer board ranks by net words per minute (คำสุทธิ), the measure Thai typing courses and exams use, rather than the English-style words per minute you may be used to. One Thai word counts as four keystrokes, each error costs ten words, and the result is divided by the minutes taken. Written out: (keystrokes ÷ 4 − errors × 10) ÷ minutes, and it never goes below zero.
That error penalty is deliberately heavy, and it is the whole reason the board does not rank raw speed. Ten words is a large deduction, so a fast run with a few mistakes loses to a slower clean one. A worked example from the Thai vocational curriculum shows the scale: 460 keystrokes is 115 gross words, five errors deduct 50, and (115 − 50) over two minutes gives 32.5 net words per minute.
Boards are separated by keyboard layout and by practice mode, so Kedmanee runs are compared with Kedmanee runs and word drills with word drills. As on the game boards, your best result is the one shown, the daily board counts from 00:00 UTC and the weekly board from Monday, and every submission is recomputed on the server from the raw keystrokes, errors and elapsed time before it is accepted.
It is the Thai typing standard: gross words (keystrokes ÷ 4) minus ten words for each error, divided by the minutes taken. It is written คำสุทธิ and is what Thai typing courses and exams measure.
Raw speed rewards typing fast and correcting later. Net words builds the cost of an error into the score itself, so the ranking reflects usable typing rather than keystroke volume.
Most English-language typing tests count five characters as a word and penalise errors lightly or not at all. The Thai convention uses four keystrokes per word and deducts ten words per error, so scores from the two systems are not comparable.
Kedmanee and Pattachote place the characters differently, so a result on one says nothing about the other. Splitting the boards keeps every comparison fair, as does separating word drills from sentence runs.
