Hmm...yes, for 2000-2008a the grooming are higher. I was referring to the
overall numbers across all years. So there is a difference between all data
and recent data on that score. Yes, across all years .62% of groomings are
between groups and 1.29% of agonisms are between groups. I've no idea why
the more recent data does not match this overall pattern. Those years have
30% of the inter-group grooming, which is a startlingly high number.
Perhaps this is a result of more grooming data being collected over time and
individual baboons showing up in more grooming pairs per average on a given
date in recent years? Dunno. After I get you the agonisms examples, I can
look at grooming data too if we think that would be helpful.

Total numbers by interact type
Thanks Niki.
I am not quite sure I follow these numbers. It looks to me like 358
agonisms were inter-group and 520 groomings were inter-group in
2000-2008? Is that correct? This looks like inter-group groomings are
actually higher (both in numbers and in proportions) than agonisms.
I think you are also showing that if you look across all years then
inter-group groomings are *less* common than inter-group agonisms (is
this the .62% versus 1.29%?).
I think it's hard to compare with just these data or get a good sense
of what is going on, except that to me these data strongly suggest
that most of these interactions are probably errors.
It is hard to know though, and hard to know quite how to proceed. I do
think it makes sense to look into a handful of them.

I follow these numbers.

This last number is a typo I assume.
