Hi Phil,

can't do that! The label can only be changed by calling setters in Python that 
are not in
the namespace you (directly) have access to in your block (you can hack 
together things
where you just hard-code the top_block's name, but uhggggh ugliness).

Also, sounds like the right job, but the wrong tool. Your block seems to be 
something like
a decimator, i.e. it takes in N samples and produces 1 value. Is that right?

Best regards,
