Your post defies mathematics, as well as logic. 110BCD means "bolt circle diameter", the key word here being "circle". Whether that circle is defined by 3,4,5,6 or however many points, it is still a circle of the diameter mentioned. In fact, if anything, a 5 bolt would have a slight advantage over a 4 bolt, due to the slightly smaller amount of metal needed around each of the bolt holes to handle the torque. You could probably tweak just a bit more with a 6 bolt pattern, in fact...
