Hahahaha, My wife would kill me, if I every evening 4 hours long after work should raid all the time
!
I do think that 2~3 mill. gold from raiding ( and collecting your gold buildings) is possible, I was a couple days back busy with raiding for upgrading my lender to lv.9 and within 3 hours I had my missing gold and had again 400K in my vault, I think I found in total 1,2 mill.
But, I already play the game too many hours and more than what I do now is really not possible considering my real life.
The high stamina is only interesting when you start with raiding, (or use your refills for it)...otherwise, you just have to wait till time fills it again, same like everyone else
