Actually I don't, I guess.
Seriously, I don't recall EVER
having a problem due to cogging because I was rolling backwards while racing. And if I did find myself in that position I could hardly blame the esc. That's like blaming a turn marshall, you know?
I have never seen any delay or stutter etc from a standstill either.
Here's the TRUE issue with the MM, and the only thing that is a legitimate knock on the system:
(The cogging problems often mentioned are due simply to the connectors on the motors.. dirty, faulty, etc) Replacing or removing the connectors cures that, period.
The only real issue with the MM systems is a very subtle and rare "glitch" that occurs coming back on throttle from a neutral throttle, such as when rolling through a sweeper off throttle and then coming back on power. It appears more as a radio glitch. It happens only occasionally in my experience... not every race, and often not once all day. It's subtle enough that most racers have not noticed, and likely it would go unnoticed on any outdoor track. The times I see it are running on a smooth indoor track.
This is a product of being sensorless, yes. BUT... that's not to say that it can't be fixed. I have seen other brands that do not have this quirk. Let's see what happens with Tekin for example. I have run several other sensorless brands that do not do this either. I've never heard of the U75 doing it. Castle is finally working on it and is supposed to have new software that is much better and should eliminate it.
If you are top 3 in the A main at a big race and a single little glitch once or twice during the weekend cost you a win.... then you have a problem. Most racers are not in that position and one glitch per day isn't a big deal. That is... if you even notice it.... as most racers have not.
