Adding Coolant to 991.1

Adding Coolant to 991.1
I just completed my 80.000 mile service. Went fine.
However, I neglected to secure the coolant cap and lost maybe a cup when I parked the car on overflow after testing. Scared the heck out of me.
My coolant dipstick is at the min level. Car runs fine, no high temps or lights.
Can I simply add a cup to the reservoir to bring it between min and max? The operating manual seems to indicate it's OK to do this, but the Pelican Parts site DYI says never add in this manner as it is a vacuum system. Have no experience with that.
I tried searching but there was nothing definitive.
Appreciate any help.
Regards,
Drew

Adding coolant to top things off will in no way introduce air, nor do you need to use the vacuum method. That's why the reservoir cap is there ! Just pour in !
If you're refilling the entire system, or have lost a large amount of coolant, etc.. yes, vacuum fill is the way.
