A few thoughts:
* Assuming you're on BT Infinity 4, the product is 300/20 not 330/30 as FTTPoD is.
* I assume these speeds are measured from a fast computer connected with an ethernet cable and with no other traffic on your network
* You probably won't know where the splitter is so keep in mind that the same GPON network could potentially be serving another village too
* If a GPON strand is split the full 30/32 ways, your "guaranteed" throughput (still not actually guaranteed due to contention upstream) is 80Mbit down. In practice oversubscription shouldn't be an issue as very few people use their connection at full speed for extended periods.
Having said that, if you're paying for "up to 300" and getting <150 most of the time, I wouldn't say that's acceptable. Have you contacted them to report it yet?
If it helps, I have 80/20 ("76/19") FTTP and typically get 73/21.
