The only thing I can imagine is that a player with a extreme low sense could notice a few fails because of it. But to be honest. I only heard about the accel with these lasermice from other members but never noticed something weird while using such a mouse like the Sensei. Even precise Flickshots are possible with it and lay in your skill.
Even top international Counter Strike Pros like the Source Player cajunb using a Sensei in important Tournaments like the copenhagengames 2012 and I know a few pros which used a buggy Xai before and not only because they were forced because of Sponsors like Steelseries.
I had a mouse with A9500 sensor and I could feel the acceleration. More than that, I knew when it made me fail several shots, and trust me, it wasn't rare.
Then again, the game is a lot faster than CS (meaning that turns of 180º to track an enemy are common) and my sensitivity is 60cm/360º.
Most "CS pros" use mid (30 to 10cm/360º) to rather high sensitivity, and as a side effect of most of them using IMO1.1 or WMO, they don't make large, fast swipes, but rather pre-aim and only make relatively minute flicks (compare that to Quake pros, making 180º flicks to shoot someone), so the chances of them noticing the acceleration are minimal, at best. I remember seeing several of those CS and CSS finals with those "oh great names" and being surprized at their hand movement. Compared to what I do when playing, they seem to not to move their mouse at all.
So my word of advise, don't get something because pros have it and it works for them. Get something that will work 100% for you and your specific needs. Those guys are paid to play a game, and they need to play it for hours straight everyday, so even if the mouse has huge flaws, they will get used to them in the end (they're gonna use it far more hours than you would at home, guaranteed). That might not apply to amateur gamers
