The idea of the golf ball sitting in a depression on the green was probably true back when TGM was first written, and helps explain why a lot of older putters had as much as 6 degrees of loft. Greens were pretty shaggy back then, but today this is not true, given advances in agronamy, maintenance and general green construction. On todays greens much less loft is needed. Yes putters have 2.5 degrees of loft, some of the Bettinardi putters have as little as 1 degree of loft. Common today of 4 degrees is probably too much.
