Attempts/Completion Statistics

[The Raven]

My Record so far:

Tube 1 CiN: Everything but Westminster and St James's Park
Tube 2: Completion just under 19 hours
Tube 3: Gave up at Wimbledon due to multiple delays
Tube 4: "The one that wouldn't die" everything but the Heathrow branch
Tube 5: Completion. Mine and Iain's current fastest time

So that's a 40% completion rate

I've made one attempt, on Tube Relief, and completed.
That makes a 100% completion rate.
(and my partner-in-crime that day didnt have a clue about the tube).

Exactly the same for me. 1 attempt, 1 completion, 100%

(And my accomplice didn't have a clue about the Tube either.)

If you give up once you go much outside your best time, the failure rate will go up as you're more likely to quit. A time that was once acceptable becomes unacceptable. For instance, Glen and I chose to quit once we were going to be over 18 hours, even though our then best was just inside 19 hours. Now we've done 17:37 we'll probably quit if we're much outside 17:30
