My data usage from self-serve shows that there are many times exact 20.0000MB or even 120.0000MB data usage almost every day. It started this bill period. How is that possible for anyone to use exact 20.0000MB multiple times on different days. It has to be a tracking error. An example is shown in the picture.

I think it's more a reserved allotment that is released again later. If you overall usage seems correct, I wouldn't worry about it.
