Hi Anthony,
i took ground + 1 wall. Which gives quarter space. Some may say distance to second wall is way below quarter lambda, so you could even take octa-space. But my K-horn experiences (which is 8th sp. calc) goes along with Bruce Edgars oppinion. 8th just doesnt work out. He blames the buildings, i tend to agree.
I know one guy who estimates about 0.707 of energy bouncing back from an average thin brickwall / wood floor. That can also xplain a lot and move theory and reality much closer together.
cheers
Josh
