Currently only showing up to 16th September (the day before the trial started).
Well a week on from the start of the trial and no sign of any movement stats at all for the last 8 days, so there's still no indication as to whether the figures when published will document the number of 3.2° approaches made.
Having said that, a quick-and-dirty analysis of landings last Friday (18th) on 27L (the only runway that's being noise-monitored) would suggest that around a dozen approaches were at or above 2500' AMSL at 7 DME, compared to only a couple on the Tuesday before the trial start (15th).
Of course that doesn't necessarily mean those arrivals were flying the 3.2° RNAV approach, they could have been high for any number of other reasons. No doubt we'll be told in due course.
