These numbers don't appear to add up.  I must be misinterpreting them.
I'll show my interpretation, then can you perhaps enlighten me with the

1.35% of all page views are IPv6.
5.32 million page views total.
IPv6 page view count: 71820

4.8% of all bot page views are IPv6
2.73 million page views from humans, subtract from 5.32m to get: 2.59m
IPv6 page views from bots = 4.8% of 2.59 million = 124320

So there were 71820 IPv6 page views total, of which 124320 were from
bots.  Which is a confusing statement.

What calculations *should* I have done, please?
