Couple of noob questions that I couldn't find the answers to.  

  In coin control I should be looking at list mode and not tree mode.  Correct?  

  In list mode each group of coins has an age, and a weight.  I'm assuming that's the stake age and the current staking weight.  So higher is better for both numbers.  
Also that the weight is really somehow calculated with the age and number of coins.  

OK, I thought the MAX stake age was 30 days.  I have a measly 20 coins by there lonesome that are  33.122 days old.  There weight is 486.  

I just received a bunch of coins and got them in one group of a little over 4K coins.    And the rest of my coins (about 1K) are scattered into several smaller piles.  Some of these are 16 - 25 days old.  

   What is the average time for a 4K block to stake?  

             Thanks for any help.
