This has been discussed in previous threads, with no-one able to provide a good reason for using them where the number of rounds is large in relation to the number of players (in my opinion). Accelerated pairings:Adam Raoof wrote:Why do we use accelerated pairings in an 11 round event? Discuss.
1. Tend to reduce mismatches in the accelerated rounds, but increase mismatches when the non-accelerated rounds start.
2. Tend to increase the number of pairings between highly rated players in the early rounds, and consequently reduce them in the later rounds, leading to a less interesting finish to the tournament.
