@illawarrior2: you actually get a stamp for each completed week or every time more than 24 hrs elapsed. if you miss a day, the stamp card is considered ‘done’ & you start over on a new one

the friend you mentioned with 143 could be due to a combination of:
i) using the bug to repeat the golden pig battle endlessly (now fixed)
ii) he/she logs in to ABE & takes down the Golden Pig regularly but not daily, causing the accumulation of stamps

What about doing the Castles? Those levels scale according to your current exp level, effectively providing the highest amount of exp available.

I usually start with the the 1st or King Pig’s castle to level up
