Approach shots over a greater distance may reflect the shape of the shot with a longer section to catch balls being fired in from a long distance.
What is the shape of golf irrigation?
Since irrigation systems have been modified for use on golf courses, the shape has swapped from concave to convex, the modern theory being that water that is shed effectively gives more control to the greenkeeper who can feed the turf with a regulated amount of water, when they see fit.

The MacKenzie green is a two tiered green with a simple straight tier drop. However, it is rare that MacKenzie actually used this in his designs and is, therefore, somewhat of a fallacy that his name is associated it. Green size should reflect the difficulty of the approach shot.

How much percolation rate for Bermuda grass?
When the topsoil mixture is compacted at a moisture content equal to field capacity on the green, and maintained under a constant head flow Of water for 24 hours at room temperature, as described by USGA procedures, the infiltration rate should be 4 to 8 in/hr. for established bermuda grass greens and 8 to 12 in/hr. for bentgrass greens. Initial rates for bermuda grass greens should be 8 to 10 in/hr. and 12 to 14 in/hr. for bentgrass greens. Since the rates will decrease a little once grass is established, starting out at the upper end of the range will allow the mix to remain longer within the desired range over a greater number of years as the tendency is for the rate to slowly decline with time.
What is the USGA's method of putting green construction?
It was a method that was a departure from what at the time was considered the norm. The use of much more sand in the topsoil mixture was advocated in order to resist compaction and assure good drainage. A principle of soil layering was prescribed that created a "perched water table", which insured a reserve water supply with a soilwater relationship considered ideal for all agricultural crops. It recommended that all soil mixtures be laboratory tested to determine particle size distribution, infiltration rates, and per cent capillary and noncapillary pore space. It stressed the physical as well as the chemical and mechanical tests performed on all top mixtures for greens built to these specifications. Though backed by solid research, this method was slow to be accepted. However, during the 1970's the method began being accepted, and now, every major new golf course being built and almost all greens that are renovated use the USGA Specifications as the criteria for determining what the physical properties of the mix should be.
