There were also some tough stretches for Berkshire where starting valuation was quite reasonable (mid 2000's) and the market return after 7-8 years was close 0% due to GFC in the middle.

I don't know what you are looking at when you say this. The longest year-to-year price flatness in that time lasted from 2007 to 2012, only 5 years, all other flat or down spots were shorter duration than that. And that one was the famous 2008 market "crash".
