One logic is, electronic would have a much higher big-events playoffs rating (very important factor) with many more maps than Niko. Electronic has 0.01 less rating in elite events, but more maps than Niko. He should also have slightly more number of big-events EVPs than Niko (both have 1 MVP each). Hence, it might seem Electronic has a solid chance for being above Niko.
However, Top4 should still be 60-40 in Niko's favour, because of having much higher overall stats in almost every category. He also has higher ratings against various TopX teams. If he had very few maps at the top level (like BlameF), then he could have been below electronic. He had decent number of maps, and better overall stats. Stats are most important in HLTV rankings. Hence, Niko is ahead of electronic, as expected.
