Sorry I missed this message previously. Feel free to keep sending over any feedback if you wish (no obligation of course). If you PM me on reddit I can send you my email address if thats easier. (Can you remind me of your reddit username as I have several messages from people there and not sure which one is you?).
Out of interest, what's your end objective with your work and the HoA system? I'm curious and excited to see what you're doing with it.
