    Hello Mateusz, I don't see any specific conditions that would disqualify this cycle from learning the Ra table. What you can do instead of trying to get update status to 0x06 with the gauge is to take these logs and submit them to the GPCRA0 tool which…

    Hello Ancy, Please use the GPCRA0 tool in order to get your Qmax and Ra table. We cannot debug with only the .gg file, we always need both the log and .gg file from before and after. Sincerely, Wyatt Keller
