Strictly speaking, yes. Although it could also be argued that 5pm-9pm is busiest peak time so p2p is more likely to be throttled more during that time. Personally, I don't use torrents.
One other point I wanted to make is about the boosts... Do you know what speeds your line is capable of? Obviously, if it's not good enough to get over 8Mb sync speeds then the speed boost is pointless - probably the sales reps will set it regardless though. Likewise for the usage boost - do you really need it? The download limit per month is 40Gb standard - if you break it you are charged £5 (obviously cheaper to pay £4 for the 80Gb boost if you know you're definitely going to go over 40Gb every month).
What I'm trying to say is don't let the sales reps talk you into subscribing to something that has no benefit or that you don't really need
