Injection quantity deviation figure after injector change MK2 1.6 tdi

Hello guys.

After changed the faulty number 1 injector to a new one, car starts to get better mpg. 

From the memory, while reading the the faulty one' deviation figure, it was like +5mg. 

Yesterday, I tried on  the cold engine, the number 2 injector was between +1.8 to+2mg.

On the warmer engine, I got following ones. Both taken while engine was in idle.

Is the number 2 injector on the way out or its in the normal range?

On the coding the injector using the vcds, I put extra 0 after the six digits like the rest injectors setting, is this correct?

Thanks in advance.
