Gidday - I took a quick look and I can't get GRT to closely correlate with your supplied data, it'll be something I'm doing wrong - its not the right time of day for me to be doing this sort of analysis ! I would say that it shows that your top load is at 71100 PSI, which in an action like the Hunter (which doesn't handle gas well) is not at all safe.
I'll try again when I'm in a better space.
