Say I would be arriving LHR T2 in the morning, take the Elizabeth Line to zone 1 (Liverpool Street to be exact), take the tube or busses a few times during the day in zone 1, and finally the Thames Link from London Bridge to LGW in the early evening, what would the daily fare cap be? (Anytime and if I use my credit card for contactless travel)

EDIT: £40.90? If yes, it seems I would be better off buying an advance ticket East Croydon to Gatwick Airport at £6.80 to be able to reduce the daily cap to £16.30 for zone1-6
