yeah, maybe you're right about ct/t side rating. this was honestly a personal opinion watching his recent matches. these stats arent good enough cause most important liquid maps are ct-sided so it could boost stats, you would need to compare or a ratio elige stat ct/average stat ct and elige stat t/average stat t or get a percentile distribution graph to realize which spot elige would be in both sides. all games that i analyzed twistzz he had way better performance as ct even on non-ct sided maps (inferno). maybe he can get a good t ratio as long as he works as last contact and confirm trades.
proactivity can boost your stat, as long as it boost impact ratio, adr, but it might decrease your dpr, kpr.
my main point is how when you are the last player, the most important won't be a godly aim, but read your opponent setup, be calm, stay in good positions, use utilities correctly. its more a brain game. xyp9x, fallen, karrigan, chrisj, for example - even shox. raw aim skills are used to get advantage in gun fights usually, like xantares, yekindar, art, elige (he's clutchy too), yuurih.
i honestly cant agree about twistzz and yekindar. for sure you can consider how new yekindar is, but this dude have been absolutely insane, a really clean xhair placement. for sure he can start to be countered or decrease his performance, but what this dude did so far this year is enough for a top 4-7 player if he keep what he's doing. furthermore, maybe we have a different concept of aiming. i consider: xhair placement, spray control, spray transfer and awareness. for me, xhair placement is the most important as long as it will guarantee you at least the first kill.
