I've been attempting to work out how ESR adjusts based on match performance, and one of things that kept bugging me was the seeming randomness of CTF ESR. A good performance would decrease it, and bad performances might increase it. Very confusing stuff.

It finally dawned on me that CTF 3 Flag and CTF 5 Flag are being treated as two different ESR values. In hindsight, this should have been obvious, given that u/SecureStreet's original post on reddit from which the "by game mode" ESR graph is based had the two game types split. They appear to be highly correlated, so it was easier for the mistake to hide for this long.

Anyway, the end result is that there's an extra category on the profile page. That's all for now!
