As you say, the network can be "flexed". The expected speeds are neither a maximum or a minimum but a rough guide.
From
this article on PN's Community site:
"The rate limits are also designed to be adaptable depending on how busy the network is, in the example above 3Mbps works when there are two customers, if a third starts downloading the ideal rate limit would be 2Mbps and if the available capacity increased to 9Mbps the ideal rate limit would then be 3Mbps again. The aim is to ensure that available capacity is split as fairly as possible between the customers using that type of traffic, maximising the available capacity with the least amount of dropped traffic. So for example on a Friday and Saturday evening some rate limits will be relaxed because the network is quiet. Over Christmas and New Year there was a lot of spare capacity that meant that virtually all the rate limits we have were removed or relaxed."
To answer the OP's question though:
BBYW Option 2 should be fine for what you're wanting to do. As has been said, PN prioritise interactive traffic and gaming is given a high priority on the network and isn't speed restricted, see
this page.
iPlayer and 4OD are classed as streaming and also prioritised with no restricions.
As for your file downloads, if it's a download site it would be restricted to around 1Mbps between 4pm and midnight but would be up to line rate outwith those times, i.e. unrestricted from midnight to 4pm (usage between midnight and 8am also doesn't come out of your allowance and is logged separately on VMBU). You can see the list of affected sites
here. The site you mention doesn't seem to be on the list, so you *should* get up to line speed all the time.
You can see your usage in the member centre - there's a tool called "View My Broadband Usage" (VMBU) which is updated regularly (about every 30mins or so).
