I am guessing, because the point of this thread is news to me, that with
fare levels increasing from January that they are seeking to ensure that

keeps the volume of auto top up transactions in the system at manageable
levels.

Changing the auto top-up threshold isn't going to change the number of
transactions. If my fares cost £20/week I'll have one top-up a week
with any threshold, just with the new one TfL will get a bit more of my
money in the bank for eternity just in case I go to Watford.

Avoiding negative balances for auto top-up customers seems reasonable
though.

But does a negative balance with auto top-up prevent you from entering
the
system again? And with the fare increases are you likely to blow the
amount
you're allowed to go negative.

I'm trying to establish if there's a technical reason, rather than TfL
having more
of my money in the bank and their "will always have enough credit"
reasoning
is sketchy.
