And to answer the highlighted point, thats exactly what I want. A robust schedule with enough slack to avoid major unreliability.

To be honest the first step id imagine you'd have to do is create some form of database logging the live times. 

I don't believe there's anything around currently. Then from there start analysing that. 

I've messed around with the BODS data and it's a bit all over the place but it's quite simple once you get the hang of it. I'm PHP not Python though.

I'd assume it's what the software which First uses does behind the scenes. 

Quite complex though mind.
