pool.ntp.org is not a server.

It is a front end service for a pool of ntp servers, that can be anywhere 
in the world.
There are hundreds, if not thousands of them in the pool.
To level the loading on the ntp servers within the pool, you will get 
assigned to a different server for each call to pool.ntp.org. 
To see which server you are actually using, you need to look at the IP 
address of the server, then do a whois lookup.

It is likely that each of your BBB's is running off a different ntp server, 
even though they all called to pool.ntp.org.

But, to get admitted to that pool, you need to be running a full 
implementation of NTP, which is cross synched with at least five other 
servers, and each will likely be less than 10 ms in error from absolute 
time.
Many these days have their own GPS receiver, so will have time errors less 
than 0.1 ms.

If you want all of your units to use the same server, you will need to 
specify the IP address of the specific server, in that NTP= statement.

Preferably one close to you, with low latency and a symmetric path.

pool.ntp.org is the Global pool.
If you want to restrict it to something closer, use:

Africa <http://www.pool.ntp.org/zone/africa> — africa.pool.ntp.org (33)
Antarctica <http://www.pool.ntp.org/zone/antarctica> — 
antarctica.pool.ntp.org (0)
Asia <http://www.pool.ntp.org/zone/asia> — asia.pool.ntp.org (264)
Europe <http://www.pool.ntp.org/zone/europe> — europe.pool.ntp.org (2763)
North America <http://www.pool.ntp.org/zone/north-america> — 
north-america.pool.ntp.org (943)
Oceania <http://www.pool.ntp.org/zone/oceania> — oceania.pool.ntp.org (113)
South America <http://www.pool.ntp.org/zone/south-america> — 
south-america.pool.ntp.org (48)
