To help people understand I thought I'd type up the examples of how
capping will work from the LU training slides. Please note that the
fare values are for now - not post 27 Feb 2005.

If you ask questions I can't guarantee to answer them properly as I've
not had the training!

I hope you find it helpful - perhaps people can see why capping has been
a complex thing to get in place.

Note that trip 2 is in the peak so its value does not count towards the
off peak cap.

Both peak and off peak caps are reached on trip 5 so the system
calculates whether peak cap is cheaper than off peak cap plus cumulative
peak pre-pay fares

Total charge for the day is £11.30 (£5.70 Z16 off peak cap plus £5.60

Please note that the above is a straight copy of the slides I have. I
will readily admit I don't fully understand the unresolved journey
examples and I can see why people may have a "reaction" to this. Please
don't "have a go" at me for posting this - I don't make the policy and
as I don't understand the logic for having it set like this - other than
to provide an incentive to touch in and out - then I cannot be expected
to take any crap for it.
