I read that using half Kelly your BR will grow at 3/4 the rate it will at full Kelly. I researched every entry in the index for Kelly in BJA3 and could not find an answer to this question. With half Kelly you should be getting about half the money on the table that you do with full Kelly, how then can you grow your BR at 3/4 the rate when your win rate is a direct percentage of the money you get into play?
