The only correlation I can find for the random gain of +1200H once a day is it appears to time with

Just to be clear with 6xVEGA 64.

4@1900H + 2@1300H (due to HBCC not enabling), total of 10200H.  Randomly every day it jumps to 11500H for a short period.  The only correlation I can find in the system logs is Windows Defender Updates.

Very strange.
