Well......I'd messaged Mick, T20, earlier, and asked his thoughts. And he wondered if it was detonating. "Can't be", I thought. Or even if it was combusting a little (as there was a feint whiff of smoke), surely it wouldn’t double the power?
But one thing I hadn't done was to run another gun over the chrono. I did a short while ago. My HW70 with Superdomes, which I'd say are a tad heavy? Result? 1.5ft.lbs. so looking like the chrono isn't goosed!

I'm going to strip and thoroughly degrease the 35. And then very sparingly relube. I might take a tad off the spring to soften it down further, also slowing down piston acceleration. 24ft.lbs out of a 35, eh? Well, I never!!!
