Seems it's not the Americans who are ignorant. Wind up is perfectly capable of providing all the answers if you wish. Mathematically its the same triangle. You miss the point: Why use a method that requires iterations to derive the answer when there's a method that gives it directly?
But then the 'ignorant Americans' tend towards the CR type which is simple to use for pretty much all problems, can solve a greater variety of problems AND in some cases requires fewer steps to calculate an answer than the CRP. It even fits in a pocket...
