3) Agree! I already had admitted the benefits of introduce something like the "transmission" parameter in the formula.
2) ???
1) More refined and versatile? Maybe I'm wrong, but comparing the two graphs (yours, and the official) yours, is starting to have readings too late in the beginning of the day (and I suspect that it starts to show zero too early at the end of the day too).
The better one, is the one which produces better results, and this may take months to determine. Hope this thread don't goes in the direction of "mine is better than yours".
Wish you a nice summer too.
