Pyramid blocks research.
In a 10 x 17 area, 7 blocks were found in 2 rows, 7 x coords apart, random y coords apart. Further testing along these 'hot' x coords found 2 more immediate blocks (within 10 coords). Will track block coords.
Reboring for a block seems to fail. Pulling a rod before cracking the block, and then retapping either by the same or different char/avitar will not find the block again. Testing to make sure coords are not randomly given blocks.
