Records set in year 2011?

3 questions arising from unusual stuff that's happened this year (in particularly recently):
1. What is the latest in the year that the bottom team, has had the best percentage of all of the sides outside of the final 5 (or final 4) positions? (North Adelaide this year made it to round 12; obviously they were bottom later than that, but as Port's percentage rocketed and West tumbled out of the 5, it stopped them from extending that run even further.)
2. What's the latest in the year that a team then-bottom of the table has beaten the then-top of the table team? (Obviously R17 in 2011; the theory being that it's more meritorious and less likely as the season rolls on, because early in the year a team can go top or crash to bottom just because of 1 or 2 big wins or unfortunate losses.)
3. Since the stat was kept, what's the heaviest 'defeat' that a club has suffered in the 'inside 50' count, but still won the game? (Norwood went 36:50 last weekend, according to the official SANFL stats.)
