BT's Traffic Management Policy on P2P Usage

1. Is there a specific amount of data that can be transfered over P2P that will then trigger traffic management, if so how much data is allowed over P2P before Traffic Management kicks in ?

or is it that ...

2. All data transferred over P2P during Peak hours is automatically traffic managed, if this is the case, by how much ...
for example on BT Infinity option 2 lets say I get a theoretical 35 Mbit per sec download speed under normal usage and I decide I want to download a file using P2P during peak hours, by how much will my 35 Mbit per sec connection be cut.

thanks in advance for any replies
