Thanks Mark,
This is very interesting results, it is ok if not 100% correct which I
think the error can be less than 10%, but I may have different
analysis of results. You concluded that homes in Europe had better
shortest distances to IETF meetings (assuming that thoes homes have
full participation of all meeting from 2009). Always Europe gets
better results because it is the favoriate meeting-location for ALL
businesses, but hope that IETF changes most of its meetings in Europe
which will serve all. I will post in future another message of my
opinion of a best practice of meeting locations which may become a
good I-D start (but need your assistance and your data results)
My analysis will discover that the past locations of IETF meetings
(from 2009 until now) does not serve-best the majority of full
attendance-participants of IETF from all regions. Thoes past locations
serve only regional-meeting-participants.
My analysis discovers that there is not close air-time-results when
comparing between homes/regions, the results variances between home
cities are large.
Overall, I suggest to consider the number of participants that are
full time attendance in all most meetings 90% attendance (not 75%).
Also to consider the number of past attendance of meetings in Europe
and Asia (there are large differents I think). These two
considerations will show that past locations of meetings did not serve
better the IETF but served some regional-interests. IMHO, two meetings
in Europe per year is a better practice for IETF activities.
