Congrats! I'm glad you asked the question as I was wondering as well. Great post (you describe it well). I have not scraped a peg. Although I wondered once if it was going to scrape when I was riding on a cloverleaf turn one time (and it was the best riding cloverleaf I had done on the GZ).
Agreed that slower riding is definitely where skill comes in. And it sounds like you've got the skills!
