[Ndn-interest] About Must Be Fresh

On the packet specification section of the website (here:  
http://named-data.net/doc/ndn-tlv/interest.html#mustbefresh), there is  
written:

The FreshnessPeriod carried in each Data packet (Data Section) is set  
by the original producer. It starts counting down when the Data packet  
arrives at a node. Consequently if a node is N hops away from the  
original producer, it may not consider the Data stale until N X  
FreshnessPeriod after the Data is produced.

Then, I do not completely agree with the last sentence. I would write  
[...]  it may not consider the Data stale until N x T after the Data  
is produced, where T is the average time requested to send the  
requested Data packet between two nodes on the path producer-consumer.

What do you think about it?
