*Arithmetic rules again, OK?*

Your sarcasm/patronization is neither warranted nor appreciated.

FYI, I ran back and forth in Worldview from early April to the day I posted to track the floes to get a fair idea which floes made it out during that time, then used the Worldview area calculation tool to measure area.

So, yeah, math wins. So does common sense: If I came up with the right answer, I had to have done *something* to get there, right? Then I posted here so people with more maths chops than I could confirm... without hostility, preferably.
