Thank you!
Sorry for posting so often, but this one really disturbs me.

What exactly "Reaction" measures?
I mean, I would suppose that, after applying
+HD,HR,DT, the
6.5*-7* AR 11 maps that are 200-250 BPM, with not necessarily easy patterns, would need much more reaction than
2.4* AR 10.87 map that is only ~110 BPM and mostly 1/2 snap, passed below 85% because my reaction was too slow and I ended up getting 100s' and 50s'.
The first example is
Shihori - Magic Girl !!(Frostmourne) [Lunatic] +HDDTHR (97.74%) played by
Rafis and gives 889 reaction score,
the second one is
Morenatsu Project. - I Will Always Wait For You (KittyAdventure) [Gone] +HDDTHRFL (84.9%) sh*t-passed by
me and gives 808 reaction score
I am trying to play highest ARs' from some time and I would say that 20 ms between AR 10.87 and AR 11, which is 320 ms --> 300 ms, is a huge gap. Much bigger than 470 ms --> 450 ms, 620 ms --> 600 ms etc., as we are slowly going down to a limits of what human can do (good that we don't have AR 12 ^^. )
Is there anything more to reaction that almost pure AR now? Look at the
889 reaction points for
Shihori - Magic Girl !! played by Rafis, that is 6.68*, 234 BPM and is really hard, then at
883 reaction points for
Tom Day & Laura Lethlean - Couldn't Be Alone (Single) (Pjecoo) [Wafu's Loneliness] +HDDTHR (96.38%), played by
AdventTechno.
The second one is 3.39*, 128 BPM and notes are placed every 1/2 beat, which makes it almost 4 times lower note density. It's very easy to read and because you are practically reacting to single notes due to low note density, I would say it's much easier to pass/FC this.
This is why my very first impression is: aren't easy maps overweighted in comparison to the harder ones? Or maybe the hard ones are underweighted?
I know that highest AR rates are very hard and needs quick reaction even on easy maps, but getting vaguely the same reaction score like extremely hard and few times faster maps looks a little weird for me? If it's not weird, then maybe it's my intuition that is advising me wrongly and Reaction is measured in a little different manner than I would expect, making the map difficulty and the need of having literally few times less time for reaction negligible, in terms of Reaction scores gained?
