Is there any relationship regarding the deployment of IPv6 between entities with ASNs of 16 and 32 bits?

Hi,
  Today this came to my mind and fortunately I knew the data existed and to locate the answer was more or less simple. I've been reviewing some data from APNIC (* 1) for several weeks (always focused on the area of ​​coverage Lacnic).
  APNIC stores a percentage value per ASN called called ipv6capable, basically is a number that indicates what percentage of an ASN has capacity for IPv6. They have another variable called ipv6 preferred but we will not talk about it right now.
  Going back to my micro study: I took a sample for three days: 11, 12 and October 15, 2014

My results (for ipv6capable) were:

Day October 15 (Wednesday)
1.34% in ASNs of 16 bits
1.12% in ASNs of 32 bits
1.26% in all ASNs
----
Day October 11 (Saturday)
1.34% in 16-bit ASN
1.15% in 32-bit ASN
1.27% all ASN
---
Day October 12 (Sunday)
1.35% in 16-bit
1.12% in 32-bit
1.27% all ASN (ASN 3313)
----

I evaluated about 2050  ASNs of 16-bits  and 1200 ASN of 32 bits. The difference between ipv6capable ASNs 16 and 32 bits is about 0.2, it is certainly a very small number but when it comes to traffic and users on the Internet these numbers represent significant volume.

My humble finding for this study is simple: It seems that there is a *very* slight preference for the deployment of IPv6 in 16-bit ASN.
