~70 average over 20 turns? Where do you see that, my breakdown for that test showed an average of 21 over 20 turns. That was spread across the full range of Luck1-3 and Misf1-3, but the irony here is that the Misf3 nations BEAT the Luck3 nations in this test. And that's not even taking into account that some of the territories that were lost in events and never reclaimed, may have had lvl0 sites in them, further depressing the Misf incomes, even though a player would have recovered the site in real play.
As I said, I WILL however be doing more in depth testing with more sets of scale combinations, though I won't do them today, I am busy testing variations on a dual bless right now, so probably tomorrow.
And again, the large/small map argument is not really the point of THESE particular tests. I am including income figures simply because any chance to gather them is useful, but the primary goal here is to quantify the benefit to your gem income, and therefore your magic capacity. In that sense, in many combinations of scales the difference will in fact become more profound as you climb over 10 provinces, as I hardly can imagine that 9 is enough to guarantee you max events each turn (on the turn 21 that I gathered my data from, all 14 nations had between 0-2 events up).
