Sorry I didn't get round to this earlier...........Anyway 2 years after and RC38 service for leaking air and general naff behaviour the forks haven't lost (as far as I can tell even a fart of air. It feels like any change I see is mostly due to taking the shock pump on and off when I check them before a ride.........to be honest I have almost given up the old habit of checking them before every ride and just do them when I remember to now! Top banana, top service, top bloke.
