Hi,

Deleting losing on time games, and deleting losing on time games and same program matches are follows.

Top rating and ELFv2 (delete on time)
   black_hole_v7        5245
   LZ_05db_ELFv2_p800   4005

Top rating and ELFv2 (delete on time and same program matches)
   black_hole_v6        4958
   LZ_05db_ELFv2_p800   3855

Top rating and ELFv2 (original)
   Katago_40b_s37_4V    4762
   LZ_05db_ELFv2_p800   3686

I had thought top rating of "delete on time and same program matches" was less than original, but it is not.

The matches between these names are deleted.
For example, if black name has "LZ" and white name has "ELF", this game is deleted.

LZ | lz | Leela | ELF
kata | Kata | KG | k40b | k160 | Ka
Zen
CrazyStone | CS
Rnz | rn | Rn
Aya
myCtest
AQ
Dirichlet
CGI
DCNN-
Odin


731369 ... number of games
721122 ... number of games after deleting timeout
592249 ... number of games after deleting timeout and same program matches

Thanks,
Hiroshi Yamashita
