Ping for comment later. I began learning bridge at age 9 watching my parents play, now at age 82, I still play regularly on BBO.
The "Minor Revamp" even helps with Party Bridge, when it is clear that you are stuck in the minors. Chapter 2 explains the use of WALSH to know this whether in Duplicate or Party. WALSH is a main requirement in ones "Minor Revamp".
I should have better formatting for the next Chapter,
