Might not the expansion be exponential (excuse me if I use the wrong word). The edge (14 Billion ly away maybe) might expand 20% but when something is only 8.6 ly away the distance moved might be inconsequential.

in fact since matter can not be created, unless there is a connection to another dimension, then the universe may expand but it has the same amount of matter, therefore imagine a distance written on a balloon. the edge expands but the distance expands at the same rate. to an outside observer it has grown but to something limited to the balloon it is the same distance.
