Well, doesn't mean he won finals, and mouse is glorous this way, they give him to market that mouse, doesn't mean it's very good option for consideration. He knows how to use equipment to win.
I don't think i like those adjustments, it has to be plug n play, little hassle, and go pwn. Well even i'm well behind the latest news.. SS has sensei 310 and rival 310, with Truemove3 stuff... which is basically new leader in sensors list, they topped logitech this time, and logi is trying to get outta their skin now, to top that, lol. They were top for 3 years, now SS time! Truemove3 (350ips max speed - overkill..) and budget Truemove1 (240 ips max speed, about right!) is basically about sensor jitter levels reduction at lower DPIs (400-800 something), what logitech didn't manage to do(!), but still logitech's best mice with top optical sensor 3366 are great, close to perfection, the tracking in quake for me is flawless with it, love that sensor (it's same sensor in Rival 700 btw). And yeah actually agree on your point of reaching perfection, after 3310(zowie, ss, cougar, roccat)/3330(cooler master)/3366 sensors and some razer equivalents, it's hard to see that much of a difference, got zowie, and you should be set with 3310, got logitech, you should be supersatisfied, maybe some shapes just wwon't fit ya, but tracking is great. One exception of 3310 - SS rival 2013 vanila version, has some sensor jitter crap, and Asus Sica with 3310 - cursor jitters just on your screen(!), the rest 3310s seemed to be without that and no spinout.

Im only interested in the sensor measured data.

Otherwise I own 3 of the old, i could frankenadder those.

Frankenmouse, an interesting idea i wanted swap Razer's top sensor into Logitech G402, because shape is godlike, sensor crappy sometimes, but that 402 is too awkward to do a frankenmouse with, g502 is more friendly, but already has a great sensor in it.. crap. Still considering to do one, skuller? Damn you still around after all those years, lol.
Another close to Intelli classic? this, with 3310, stable as hell, shape glorious, clicks a bit mushy compared to Rival 700, still saving it until MS offers some real good sensor in their Intelli..

when a better sensor than PMW3366 or hero gets made, call me.

Truemove3 (more IPS & dpi & 1 (less IPS and dpi), mate, but 3366/3360 are already great!

maximum linear acceleration?

Buy typing this did you mean: "is it max control speed of a mouse swipe as fast as you can without changing direction?"

btw, there are also benefits from the negative accel on the original.

Where did you find neg accel useful in the ie3?
Some more nerdtastic data of MouseMovementRecorder, dunno, if you can read this graphs, i'm not really sure myself how to read thsi, knowing IE3 is with a good sensor, the more reports of 1 x -1, the better, i believe, haha, correct me if i'm wrong.
