It's worth bearing in mind that the reasons for missed approaches at Gatwick will vary somewhat from those at Heathrow, for example. In the latter case, it's more likely to be the preceding landing aircraft being late to clear the runway than an aircraft slow to get airborne (though of course that can happen too at Gatwick with consecutive landing movements). Other reasons for GAs such as unstabilised approaches obviously apply to both mixed-mode and segregated operations.
As it happens, both LGW and LHR have recently published GA stats for 2015: Gatwick had 520 from 134K landings and Heathrow 591 from 237K arrivals.
