I visited Thorpe yesterday and rode Hyperia twice, but queued three times.
My first throughput timings were taken from the main queue at around 11am, just before Hyperia suffered a 10 minute down period (train on the brake run hadn't returned to the station, car wouldn't release from the drop, block section in effect).
My second throughput timings were taken from the single rider queue, where I was far more stationary and possibly better positioned to get more accurate timings. I'd separated from my gaggle as they wanted to do Saw: The Ride, they joined an advertised main queue Saw at 30 mins, rode that followed by Samurai. I joined the Hyperia single rider queue (as a single rider, main queue at 60 mins), which was on the final "straight". After not even reaching the steps after 45 mins, I bailed. (New pet peeve is groups joining single rider, full families included). I actually saw a group, who had joined the main queue as I joined SR, lap me and make it up the stairs. This triggered my bail.
The weather yesterday was absolutely shocking, but Hyperia performed relatively well. It didn't stop because of heavy rain, it kept going with sight warnings issued over the loud speakers.
When I timed throughput on re-opening day, Hyperia was pushing around 920 pph. Yesterday, as you can see, it was around 200 pph less.
The train is inching from the brake run, into the station, far slower than I observed on reopening day. The train will leave the station and there's at least a 10 second delay, up to 15, before the preceding train re-enters the station. I believe it's this that's causing throughput to suffer, it's also responsible for yesterday's block section stall. I'm not sure if this was due to the weather, but getting the train back into the station appears to be a bit of a problem.
