How many ways can you skin the "Points Per Position" cat?

Points per position (PPP) is suddenly becoming more popular as more sections adopt it in reaction to the 40 & Over division going to a 4-court format.

I've started taking a look at what points are most commonly used, and it appears there is no standard and there are a wide variety of allocations used.  It appears each section/district is given leeway to do what they see fit, and opinions vary widely.

Here is a list of all the options I've seen for 5-court formats:

• 1,1,1,1,1 - Eastern, Midwest, New England
• 4,3,2,5,3 - Middle States
• 5,4,5,4,3 - Middle States
• 5,4,6,4,3 - Eastern, Middle States
• 5,6,4,3,2 - Eastern
• 5,6,5,4,3 - Eastern, Middle States
• 6,4,6,4,3 - Eastern
• 6,5,6,5,3 - Eastern
• 6,6,5,4,3 - Eastern

That is quite a collection.  But there are quite a few for 4-court formats too:

• 1,1,1,1 - Eastern, Mid-Atlantic, New England
• 1,2,1,1 - Northern California, Pacific Northwest
• 4,3,5,4 - Middle States
• 4,4,3,2 - Eastern
• 4,5,4,3 - Middle States
• 5,4,6,4 - Eastern
• 5,5,4,3 - Middle States
• 5,6,4,3 - Eastern
• 6,6,4,3 - Eastern
• 6,6,5,3 - Eastern
• 10,6,4,2 - Texas

And for 3-court formats:

• 1,1,1 - Eastern, Midwest, New England
• 2,2,1 - Eastern
• 3,2,3 - Middle States
• 3,4,2 - Middle States
• 4,3,2 - Eastern, Middle States
• 5,4,3 - Middle States
• 5,6,4 - Eastern
• 6,4,3 - Eastern
• 6,6,3 - Eastern
• 7,4,3 - Middle States

Now, it is worth noting these allocations span different court formats, not all 5-court formats are 2S/3D, nor are all 4-court formats 1S/3D, etc.  But there is still a lot of variations, no one seems to be honing in on the best allocation to use.  And my image above is woefully under representing all the allocations out there!

What do you think?  What is the preferred allocations to use?
