I notice that on chat, a user's reputation equals the sum of their reputations across all SE sites; whereas flair reputation equals the sum of reputations just for those SE sites where reputation is greater than 200. Is this difference in calculating rep deliberate? And if so, why?
I note that until about a year ago, Area51 showed rep on all sites (as chat does now), whereas flair showed the sum of rep only on sites where rep>200. After a discussion here on meta, Area51 was changed so that it conformed with flair. Can the same happen with chat?
