Red Sea Test reagent amount question

[ScubaSkeets]

I picked up a Red Sea Calcium, Alkalinity and Magnesium test kit.
Instructions say that while the tip is on the syringe, fill the syringe up to 1ml.
If the tip is on the syringe, doesn't that mean that you're actually adding more than 1ml in order to reach the 1ml mark on the syringe? Maybe that extra very small amount doesn't necessarily affect the test much, but im sure it does a little, no? Or I wonder if the company put that into consideration. If it didn't, wouldn't it be better to fill the syringe first and then put the tip on it?
I'm an analyst, so maybe I'm just over thinking things

You pull the plunger until it reaches the 1ml mark, not the fluid.

If you pull until the fluid reaches the mark with the tip on, it would be more than 1ml.

From what I read from Red Sea the amount of volume in the tip is taken in account for so you don’t have to worry about it.
