Their is a simple reason for the 0.95 factor involved in calculating the 
lenght of a dipole: the speed of light moves slower in air than in vacuum.
The 0.95 factor is the speed shift.

Second, that formula is an approximation. (a very good approx.) Most of us
cut the lengths on the long side and tune (cut) it as close to 1:1 on the
SWR.
