How do you work that out? Please enlighten me. 2^24/2^128 x 100 is  
many orders of magnitude smaller than 2^24/2^32 x 100:
	gromit% bc
	scale=50
	2^24/2^128*100
	.00000000000000000000000000000493038065763132378300
	2^24/2^32*100
	.39062500000000000000000000000000000000000000000000

There are of course the same number of IPv4 and IPv6 /24s.
