I think it depends on what time control you play. I play live 10 0 and never face an opponent 200 points higher or lower.
However, you are evidently playing something where there aren't a lot of players looking for games. When there aren't many people looking for games, you have to take whoever comes along.
Useless - it takes any player no matter what you put
If you say only -50 points it starts games with - 200 points
Why do I bother
Just get rid of the custom parms or go to the playground and find a five year old to do you coding
I don't want to play people 200 points lower
