Sobre esta calculadora

This tool provides a simplified preliminary calculation for DWZ changes. The official DWZ system may consider age, game history, and other parameters. The value shown may differ from the official DWZ record.

Para jogadores sem DWZ

For players without a DWZ value, the tool can show a starting performance. The official first DWZ value is determined by the German Chess Federation.

Como funciona o DWZ

Pontuação esperada:

E = 1 / (1 + 10^((Rb - Ra) / 400))

Novo rating:

R'a = Ra + K × (S - E)

Simplified development coefficients: E=30 for new players, E=15 for experienced players rated 2400 and above.
