Shooting H1000 after H4831sc

[1KBR]

I have worked up a good 600yd load with H4831sc for my 6.5/284 and another hotter 1000yd load using H1000. I hope to experiment with firing one load after the other to see if different types of powder fouling have bad effects after this weekends shoot, but I remember seeing a chart which someone made up a while ago about which powders can be shot without cleaning after using a different type of powder. Has anyone experimented with shooting H1000 after using H4831sc?
I know most will say to clean between powders, but my barrel takes a number of shots to settle after cleaning.

I was wondering the same thing about a different caliber, same powders, and found this thread.

No info about H4831sc to H1000 in the linked thread though and I couldn't find the thread in the USrifleteams forum either. Did you end up shooting the different powders at the match? How did it go?
