I'm not sure about staking at all. I've got 20 odd clams in wallet 3500+ confirmations. I have 0 clams staked...I just leave wallet online.....am I missing something here?

What does that show?
Your 'weight' looks wrong - too low.

Why at 40 clam weights over 500
I can transfer all Clam in a new purse
Your "weight" is what you get when you add up ((the age of each output in days minus 4 hours) multiplied by the size of each output in CLAMs)
Each time you move coins around, their age goes back to zero, and so you lose weight, and your chance of staking goes back down. So it's best to leave them alone.
With 20 CLAMs, your weight should go up by 20 every 24 hours. Is that what you are seeing?
