I received this delightful response to the reader's question in Ask Linda #291. While it is not a question, per se, I found it an interesting read. I hope you will enjoy it.
Having thoroughly enjoyed over 20 years of the best form of golf (4-ball) I would say that the 3/4 handicap rule is a great deal fairer than full h/caps. This is because the higher h/cap player is almost always less consistent. This reults in her/him on average losing individual holes by more shots than when she/he wins a hole.
