If we can condense into 1 turn that section of the Nordschleife between the big paved hairpin and the final right hander onto the main straight, for whatever reason my brain just cannot latch onto anything in that section to memorize, no matter how many times I've been round it. I just end up approaching every turn as if it's the first time, too tentative, and it loses me a lot of seconds going through there.
The rest of the circuit I could give a good go of knowing off by heart, but that section just terrorizes me
