How long have you been asking every 6 months? I did my first ever CLI in February and I'm thinking about doing a 6 month wait in between as well.
With Disco every experience is YMMV. Getting 9.5 k increases on two 6 month intervals is just what Disco was willing to give you at those specific times. Having long history and 800 scores has very little to do with it imo . Disco be Little Drummer Boy
