I have tried this, double and triple checked my calculations, but answers were all deemed wrong and now I am locked out. My research suggests that there might potentially be different constituent answers in a couple of cases, although my answers that took account of these potential variants were still wrong. It is possible I have made an error somewhere else, but having double-checked I'm at a bit of a loss.

Law 37 mentionned that there may be problems with some of the tricky puzzles. You should email support

It took my first attempt.  For the most part, the terms, as worded in the puzzle, produce unambiguous results in the US version of Google.

Edit for clarity: I was talking about "Laws Laws Laws".

Well my second opinion introduced other possible answers so its probably not an OSC support issue, just my answer being wrong. There probably aren't that really that many possible answers so I will try again tonight. Between us, we have two possible answers for the Guiness consumption, three possible answers for the walk across town, and two possible answers for the pampering session.

I thought I had this one (Tour of London) nailed when my calculation was, to the minute, matching one of the Shelford arrival times.

Sadly, it wasn't that one or either of the times adjoining it.

I'm wondering if the time tables looked different when "There Will be Blood" was showing.

Because the puzzle says, "At what time did I get back to Shelford station?"

What do you mean Molnar?

I'm having much difficulty tracking down the hair glossing treatment. No suitable websites... Grrr

I don't know how to say this without giving up the ghost (and we may be talking past one another), but

Edit: Ok, I had guessed a length of time for the hair service and got the right arrival time .  I just found the value I was supposed to use and that would give me the wrong answer.  Go figure.

@Molnar:

I think I get what you're saying.

But we'd have to ignore the constraint imposed by National Rail.

(Which I 'm pretty sure we need to do for the movie.)

If we need to use specific information available only at the department store, shouldn't it follow that the same would apply for the train schedule?

[coffee] I tried it again using the correct pizza time but stil nothing, and to make it worse, I've been locked out! Never mind though, because I am now 11th place

Afraid not. I'm waiting for someone in my team to solve it so they can help me out

I got that aswell Tamzin.

So many possibilities-think I'll give up on this one

Here's another one where, having failed with my calculated answers, i have systematically tried everything between 17.46 and 18.30. Is it somewhere within this timeframe and I must have gone wrong somewhere (the link crashes a fair bit), or do I need to keep trying new ones?  

Thanks Andy. I suppose from the wording "they started the treatment" and "feeling pretty pampered I left Selfridges", I assumed they had been through the treatment. I'll recommence in a new time zone tomorrow! 

This one has officially cheesed me off! I have now clocked up about 50 attempts for this measly 100 points, and still no joy. Variously confused by erroneous pizza-eating times, non-existant hair treatments, lack of clarity over there will be blood times at a certain cinema, and the vaguaries of british rail train timetables, I am still none the wiser on the answer to this. Even more annoyingly many people seem to have got it on first attempt, despite overlooking important nuggets of information - see above, and Molnar's use of "The Force" (wish I had that).

Can someone narrow it down to a 6 minute window, so I can guarantee getting it before the final puzzle is solved please? It must be somwhere around
