Prolly good to post final solutions for future goog'lerz (like when i
forget) or anyone who was following along.
Here's where i ended up with this... shows both ways.

I actually find the map biz easier to get my head around than the list
comp. I guess this makes it another good reason for me to be happy
that map is apparently staying in after nearly being depreciated. I
generally prefer list comp in every instance, but the idea of an if
else construct wi

I guess it all depends on your desired level of precision!

Yeah the list seems flaky at the moment. Additionally, my query is an
incredibly stupid one. But what you have works and represents an
improvement over the unreadable kludge I was doing. Thanks to all who
responded.

I can think of about 80 billion reasons why you would encounter data
outside your grid, esp. if you aren't the original producer of the
data. Imagine you are mapping something to color (RGB values) or you
are doing a signification of volcanic activity or the big bang or the
earth's magnetic
