It is entirely possible that Google's numbers are artificially low for a number
of reasons.

AMS-IX publishes stats too:
       <https://stats.ams-ix.net/sflow/>

This is probably a better view of overall percentage on the Internet than a specific company's content.  It shows 
order of 0.5%.

Why do you think Google's numbers are lower than the real total?


They are also different stats which is why they give such different numbers.

In a theoretical world with evenly distributed traffic patterns if 1%
of users were IPv6 enabled it would require 100% of content to be IPv6
enabled before your traffic stats would show 1% of traffic going over
IPv6.

If these figures are representative (google saying 1% of users and
AMSIX saying 0.5% of traffic) then it would indicate that dual stacked
users can push ~50% of their traffic over IPv6. If this is even close
to reality then that would be quite an achievement.

There is even more complexity.  Remember the 6-to-4 stuff?  Suppose a user on Network A used a tunnel broker on HE, and 
his traffic passed over AMS-IX encapsulated in v4?  He would show up as v4 to AMS-IX and v6 to Google.

Lies, damned lies, and graphs. :)
