At Area 51 my 'live update' (6th in the right column on my "Definition" tab, for a beta site that I followed) says I have 1 gold, 53 silver and 269 bronze badges.
My Flair Badge (updated today) says I have: 1 gold, 52 silver and 263 bronze badges.
If I run this SEDE Query: "Total # of badges by 'color', for a single user networkwide" it says I have 1 gold, 71 silver and 437 bronze badges.
That's in agreement for gold, but 19 silver and 174 bronze badges more than my global flair (and not accounted for by adding sites with less than 200 reputation).
It's not impossible that the extra badges for the SEDE count are duplicates, but I thought global flair has dupes included. Not sure why the Area 51 count is far ahead either, since my global flair badge updated today.
It would be preferable (correct?) if the Area 51 count was used, or is SEDE closest?
After Rene's SEDE Reputation Calculation was proofread by Glorfindel I re-ran it yesterday and a few minutes ago (updated 18 hours ago) with these results:

Area 51 reports:
According to my Achievements Feed I earned 2 bronze badges yesterday and none in the prior several days. Our Flair images remain behind all other calculations of its value.
Proof that the Flair image is lower for other users too.
