Chandler – It’s not the WA who isn’t recognizing it. It’s the USGA. Toss out the bad rounds, always. Simplest way I can address the PA vs. MB topic is that a handicap is similar to a credit score in that it is universally known. It doesn’t matter what factors went into it, you can take that number anywhere and a bank will know the interest rate (or strokes) to give you based on it.
Currency may be a better example. You take your $100 US and travel to Italy where they give you $90 Euros to exchange it. It feels different because you’re in a foreign country and the quantities are different. But it’s actually the exact same amount of money.
The differences in playing conditions are perceived difficulty, not actual difficulty.
