Impressive - I would have to check on the map for almost all of those because you clearly know them better than I do! I can tell you without checking that for #3164 no. 5, bear in mind that I set off from North London (in the dark) and rode all the way down there, and that one's quite a lot closer to (my!) home...
Ah yes a fair assumption, but no I was just moonlighting down that way and getting my miles in! I don't want to just give it away in case someone else wants to bag it, but you're 85 miles out by bike according to the route Google maps would send you to get from your guess to there!
