Working vertically upwards from the roof of the King's Chamber M&R have vertical heights where you have ".5 units" of 3 metres, 2.7 metres, 3 metres, 3 metres and 3.56 metres. However this whole area is subject to doubt as measuring is very difficult and no one knows how thick the top angled blocks are so that is pure speculation and looking at M&R's drawing I can't see that they give any measurement.
