And to address your question regarding HSR and hits registering - there's still quite a bit of work to be done before HSR works properly, and not just with SRMs. I've noticed shots that I've aimed directly at a shutdown 'Mech's center torso that completely fail to register. I'm sure they're working on it, but it IS a problem.
As to you having noticed this issue in the Training Grounds - that's surprising, because TG launches exist completely on the client-side, meaning HSR doesn't play any role at all. You should most certainly take video of that happening, if you can. If you don't have video-recording software, I recommend using MSI Afterburner - it's completely free and a really useful program.
