Applying Markwell's Selective Criteria

This post got me thinking about my own Selective Criteria:

Markwell


What the premium membership WILL do is allow you to be more selective on the caches you choose to hunt.

From my December 1 pocket queries, there are 3,467 caches within 20 miles of my house.
Of those 3,467 caches, 435 are temporarily disabled leaving 3,032 caches
Of those 3,032 caches, 309 are not traditional leaving 2,723 caches
Of those 2,723 caches, 1,479 are micro leaving 1,244 caches
Of those 1,244 caches, 124 are not chosen in their size leaving 1,120 caches
Of those 1,120 caches, 79 are terrain=1.0 leaving 1,041 caches
Of those 1,041 caches, 107 are difficulty=1.0 leaving 934 caches
Of those 934 caches, 39 are are ones I've found or placed leaving 895 caches
Of those 895 caches, 144 are placed in a parking lot (based on my scouting reports) leaving 751 caches
Of those 751 caches, 13 are terrain>=4.0 leaving 738 caches
Of those 738 caches, 26 are have a size of "other" chosen leaving 712 caches
Of those 712 caches, 509 are excluded based on other criteria I use in GSAK (polygon filter, number of recent DNFs, etc.) leaving 203 caches.

That criteria gets me down to about 5.86% of the caches.
My Selective Criteria results:
  • There are 689 caches within 20 kms of my house.
  •  Of those 689 I haven't found 313
  • Of those 313, 303 are enabled (10 are disabled)
  • Of the 303 when I exclude micro, unknown and other (because these almost never are swag size) I get 136
  • Of the 136, I exclude the following cache types: earthcache, whereigo, virtual, gps maze, event, project ape, unknown, and webcam (not my cup of tea but if I can solve an unknown cache I'll hunt for it as long as it's swag size). That leaves 13 caches
  • Finally exclude any cache with a D/T rating of more then 3.5, that leaves 8 geocaches.
8 geocaches within 20km that meet my criteria. I think I may be a little pickier then Markwell. 
That criteria gets me down to about 1.16% of the caches.
