Perhaps Paul (Corfield) can answer this one
(enquiring minds want to know).

Surely with Auto top-up I'll always have enough credit to make a
journey as I'll get topped up when I enter?

Or is it the scenario where I have £5.10 left and make a £7.30
journey to Watford Junction from Zone 1 that leaves me in negative
balance that makes me unable to enter the system again.

Does Auto top-up work when your balance goes negative I think is the
underlying question.

If it does, why the increase to £8, or is it to protect from a very
large
(impossible) negative balance?
