EV over 2% possible?

I had been on a different thread in which Don had nicely provided the results of a game that yielded a ev of .94%. I am not going to provide all the criteria as my next question in regards to maximum ev.

Is it ever possible to eclipse 2 to 3 percent with optimal conditions in place. If so, what type of game, spread, or conditions would it take in order to achieve a higher ev?

I know that a 1%-1.5% is capable but not sure if you can get much higher than this.
