You are overwriting eWithDeltaL with [] every time. You should have the assignment of [] to the variable only when you know that you want to reset the variable.

When you declare a variable as persistent, it is automatically assigned [] if it does not already exist. You do not need to initialize it to [] unless you want to reset it.
