Tournaments that incorporate handicap systems

A great feature of shogi is its handicap system. I am searching for ideas how this could be incorporated in unrated tournaments, so I can suggest this to the lishogi developers. How the handicap system would be assigned would depend on a player's rating or instead at the start of the tournament by having rating pools or groupings. Please respond with your comments and suggestions.

I think the most commonly played handicap is 2-piece. But what do you suggest should be added?

Perhaps every 100 point difference in rating would trigger the next step up the ladder in handicap. There are 23 different types of handicap in the board editor. Perhaps 4 groups of 6, so that requires a single position is in 2 groups.

100 point different - Group 1 (Computer randomly chooses from 4 starting positions with the lowest handicap)
200 point difference - Group 2 (Computer randomly chooses from 4 starting positions with the next lowest handicap)
300 point difference - Group 3 (Computer randomly chooses from 4 starting positions with higher handicap)
400 point difference and great - Group 4 (Computer randomly chooses from 4 starting positions with the highest handicap)
