“That's also why part of the London City approval for many types is that each landing counts as up to two "normal" landings when calculating things like gear life limits.”
What absolute rubbish.
Operations at LCY are based on a relatively normal landing flare and touchdown.
Several years ago, the FAA measured a range of aircraft types and operations to determine/check landing gear specifications; the tests at LCY filmed BAe146 operations. The results showed that the range vertical speeds at touchdown was equal to or less than many wide body aircraft landing from a 3 deg approach.
