I know that there's quite a lot of existing questions about reputation count discrepancy but I want to point to a particular issue so bear with me please.

The situation is:

1. On 17 Nov, I received +200 reputation.
2. On 18 Nov, I received +225 and also got -15 from a reversed answer approval. This was an asnwer I gave on 17 Nov.

Now, on the reputation page it shows that I got 185 and 225 reputation respectively on those days:

But on my profile page, the graph still shows 200 and 210. This discrepancy makes it hard to check reputation, e.g. for Epic and Legendary badges (the reputation page shows the correct value for that). Also, it doesn't seem to be hard to fix the graph if the correct values are already calculated somewhere else.
