You missed that 146 clear by Barb. CompletedTime timestamp is 1578023227000 or GMT : Friday, January 3, 2020 3:47:07 AM. I don’t understand why you would use any data source other than Blizzard’s API.
This means Barb is probably getting nerf next patch.
This was a blue post commenting on Crusader doing solo GR 146 on EU non-seasonal.
This barb from CH did 146 solo with 9477 Paragons.
