True, player behaviour has a large effect on this number. But only 2 categories? I’m not sure…
My longest raid win streak is 72. I am an economic raider focussed on filling the hero chest. My food supply is near infinite, so I cycle through many targets until I find one that I can comfortably beat.
I do stick to diamond, for better chest loot. No cup dropping, I have never done that and never will, because it makes me feel better - I know, something about honor and foolishness. I maintain a strong defence team, if I stop raiding I bottom out to 2.300 to 2.400 cups.
I typically hit anything with a team score that is 100 or more lower than mine. For my skill level that is the sweet spot resulting in a lot of wins in diamond without having to spend too much time (a much more precious resource for me than food) cycling targets.
So that 72 number is influenced strongly by my economic raiding. I don’t look for the biggest challenge I can find. I don’t drop cups either. I economically raid just a little below my weight for optimum success rate and chest loot. And that more often than not results in a win.
