I'm wondering if that 21 grams, at 16 seconds, was your first dose of the day?
In any event, your experience simply verifies that you really should weigh each dose, in order to insure consistent results.
I'd also suggest trying nixter's tip to "try dosing lower and grinding finer if only to see if it affects your static."
