I manage a scrabble group online, the ELO is set by Mattel but that is not a handicap just a grading Mattel gives.
In my group we run a weekly League , Monthly Lottery type game (who you play is based on numbers drawn) Tournaments for three different sections of the group and numerous friendlies. The group is holding at 80 members with ELO from 950 up to 2200. To make it fair and so that the big ELO are not always smashing the little players I have tried to devise a handicap based on the ELO but its causing problems because the bigger end are now losing games because of the handicap but are still winning the Mattel game which is increasing the ELO further. I attach what I have tried to use but can anyone suggest a tweak of the upper levels that are fair to the player but still give the little man a chance to win?. Thank you
