"Just under one per cent of all Oyster and contactless journeys involve
a card clash and we are seeing this number continue to drop each week."

Sorry, but 1% seems very high.

My experience of card clash is an error 94 & the gates don't open.

I didn't think that gates were enabled for contactless cards yet.

Given there's a not-insignificant trial running, I'd suggest they are.
