Something about that bothers me, which is why I wrote what I did. It's probably the weak link (in your theory) between these ESP powers and the reality. Moreover, you can't return the uncertainty once the power has been used already because that has become the real reality already at that point. It would make sense he could render someone unable to use the power when touched, but it doesn't make sense an already altered reality could be returned to the "normal" state. Well, that seems to be the case with Accelerator and the shit flying around, but Mikoto's case still fights againt this in my opinion. Also the fire used by Stiyl, The Fire Mage.

There seems to exist a discrepancy between how matter and energy are treated in this series.
