What does Elo mean?
DevelopChess Elo is your training rating, separate from Chess.com, Lichess, or federation ratings. Eligible practice changes it according to the result and expected difficulty. Notebook reviews do not change it.
What does Chess DNA mean?
DNA records points earned or lost in your training areas. Points build levels. A lower total can mean less practice; it does not by itself prove a weakness.
What do area ratings mean?
An area rating summarizes eligible results for a pattern or skill. It appears after ten attempts. Before that, “Most practiced” describes activity rather than proven strength.
What does consistency mean?
Consistency counts recorded active days and activities. A streak describes your practice rhythm, not a guarantee that your playing strength increased.
