[PD] block~ and effective blocksize

[intent]

Hi,

I made another discovery connecting the output of "env~" then "line" 
to a bang message and counting them during 1 second.

I get 93 bangs for "env~" and 50 for "line".

But i don't understand, it cannot be 20 ms update time for "line" since we 
are doing ADSR with it (?)
