I’ve had green lights in under about 10 seconds for about a week now. I must have used a dozen different docking stations in that time too, so it doesn’t just seem like luck to me.
My guess is they have finally fixed (although never admitted broken) the caching of members details at each terminal. Either that or a huge number of annual members haven’t bothered renewing.
It would be interesting to get some inside info on what’s going on.
