I tried googling RFeK, along with some other keywords, and seem to only come up with this Facebook post which presumably is written by you given you give nearly identical arguments and numbers and both claim to be LEED-credentialed engineers and/or scientists. So RFeK seems kind of ill-defined to me.

16.3°K/288.8°K x 200/25800 = 0.00044°K

This equation seems odd. You've taken a ratio of temperatures (unitless) and multiplied it by a ratio of RFeK (unitless) and gotten a result with units of Kelvin. You've either neglected to include some sort of constant that you're multiplying by (I saw 103/410 in your previous comment, but what exactly is this? Does it have units of K? Where does it come from? Why does it seem like you haven't actually used it given I just typed your numbers from the equation above into a calculator and it does equal 0.00044?) or this is wrong.
