Placement declining but kill-/damage numbers rising

Hi all,

I´m monitoring my rank-progress for a while via Excel, using the TRN-webpage.
Since the end of September it seems like I’m growing rapidly in terms of kills and damage, but my placement is dropping visibly.

F.e.: End of Sept. I was listed as rank #12.791 in terms of overall kills. Today I´m #14.814.
Same for overall damage or wraith damage/kills. Although I am active in the game every day and bring home between 3 and 15 kills per match.

What´s the reason for that?
New data? More players included in the tracker?

Btw. those placement-numbers are global? European only? PC-only or platform-wide?
