  <p>I also noticed that, in the meantime, the shorter the time control, the lower the median is vof all players. I think it is because, the shorter the game is, the more you need to know by heart many openings and the more you need to be skilled to be good at such mode.</p>

Comments.Text: One factor could be that you need an arbitrary baseline. When blitz ELO was invented, maybe just the OTB ELO was copied over. This might have introduced an error (nothing guarantees that the two *are* the same), with the result that now the blitz ELO is constantly higher (which would be nothing strange - e.g. the ELO is constantly higher than the national German rating, so such effects exist).

For high level chess, blitz has an 18.5% draw rate compared with a 30.8% for rapid, and 36.9% for classical.
