2015 Lancer Radiator coolant

Just changed my Coolant today you all. i got say 3.8L out of it, Book says 7L is in it ?
Well i did what i seen on Net to do.
Just turn the tap open on the Radiator and tip out what was in the recovery bottle and all good ! but not 7L ?
I think i will do the same in 2 years just to be sure ? i will not go 7 years to do it again, even tho this coolant says 10 years.
I have 54.000KM up on it now, all good !

Anyone think i done the wrong thing ? should i do the same again in 6 months or so.
I did not use tap water, but rain water and coolant, 50/50.

The old coolant looked good, nice and blue.
