At some ungodly hour this morning the TMS summariser (might have been Mike Selvey) observed that Giles' typical delivery on this tour has been a full 10% slower than his typical delivery from before his lay-off: the same sort of difference as there is between (say) Hoggard and Flintoff, or Anderson and Harmison.
The figures he gave were 50 mph and 55 mph.. and whilst I've no idea how scientific his stats were... he joined with other observers in noting a clearly visible change in the bowling... and went on to applaud his impressive (and often under-rated) efforts in the series to date
