Sending raids and cancelling... yeah... forget that...
In an average week you have 10 raids per day (24 hrs) = 70 raids
Add the 30 extra raids for the brawl = 100 raids
If you are clever (or just plain OCD) you can push up to a further 19 raids into the new "ranking" week by sending them out before the cut-off but making sure they hit after the cut-off.. you do this by slowing them down... add a pikeman to the raiding party!
This makes a max. no raids 119 per week... at 100k per raid total max res = 11.9 mil.
Now ... here's the kicker!!!
Every now and then Plarium throws in a "Capture the Flag" Tourney.. prizes for doing well are league "buffs" including extra raids for a week ... usually 5 extra per day... sometimes even 10 extra per day...
The screenshot you showed for the rankings are from the week after the last Capture the Flag tourney... hence the "impossible" numbers...
P.S.
The player ranked #1 bagged 16.3 mil res... in other words... they did ALL 10 raids per day + ALL extra buff raids per day + ALL 30 extra raids from the brawl + (assuming they bagged 100k per raid so no "failures") timed an extra 13 raids from the sunday before to hit in the "ranking" week.
That is true dedication to one's craft!! deserves a standing ovation... at least!!
P.P.S.
I just re-read your post Fri night/Sat morning?? ... that's even more impressive (clearly buff is more than 5 per day)
