one wing, or as many wings as you like, its calculated as a percentage of the total horizontal areas and is an easy process....

I work on 20% and 25% areas... 22.5 % always is fine for flying...

Funny you mention that. Flew the maiden of my recent build over a small field of tall grass...lots of rain these past two weeks... and it crashed on the only bare spot in the field.Oh and it also looks ugly now.

That only happens when you are not holding your mouth right...

When I want a test glide I do a chest high level push/launch with elevator and ailerons leveled and use enough arm speed to get it up close to a landing speed. And look for a steady level descent to the ground.

If that looks about right, I add a little power and do it again hoping for a continuous low level flight.

I almost always have used my CG stand at home and know that the CG is realistic or close to right if I know the location
