Ignition timing

in H2
Hi,
could somebody please explain to my why the maps for different countries use different ignition timing?
I don't get that. Why not use the same ignition timing settings for all countries??

I see now that the same question was answered in the previous thread.
Emissions based? Ok that could be it but now which country map has the best settings?
Hi,
I do not have a good answer for you on that as I have never taken mapping from different countries and tried them all back to back on a certain bike. Maybe someone else on this forum has...
Thanks,
