Wrong percentiles in the MMR graph

[marco93f]

Percentiles in the mmr graphs aren't quite correct, and that happens across all seasons. For example, looking at season 1 EU, we have the following mmr/percentile correspondence:

• 1625 mmr (Highko#21217) = top 19.5%;
• 1600 mmr (bokma#2890) = top 21.5%;
• 1575 mmr (Dexttt#2399) = top 23.6%;
• 1550 mmr (Mbolibombo#1407) = top 25.8%;
• 1525 mmr (steiLz#21872) = top 28.1%.
  But:
• the second purple bar (top 25%) points out to ">1625" while it should point out to ">1550", because it's the closest to 25.0%;
• all percentiles from the cumulative graph are also wrong. Just compare the values above with the ones in the graph (>1625 has 23% instead of 20%, >1600 has 26% instead of 22%, etc.);
  Also, I had myself exactly 1725 that season (marco93f#1535) and looking at the graph I fall into the >1725 range. I should either be placed in the range prior (>1700) or the ">" symbol should be replaced with "≥".
