re: My personal feeling on precision (not accuracy - still waiting for you to figure out what "accuracy" means)...
"But (just like where you can add multiple images together to get more information than the number of pixels captured in each individual image) when you add the information from many many cores to your dataset, you can get more precision from the system than any one core could provide."
How many bore holes had been made in various areas in Antactric or Greenland and do you have a reference or keyword [what is this called] that would find more information about this?
