If not I'm planning to give it a shot. Going to start by comparing stage1 timing tables to the stock timing tables, multiply the differences by a small amount, and apply to my new 93 map. Check knock and incrementally repeat. When I do see knock, pull timing 1/2 degree and re-check.. Seem like a sound approach? Any other advice? I'm a software engineer so I know how to approach things empirically, but I'm learning so any tips would be greatly appreciated.

You might start by checking your logs for the base map. Unless you are always staying at an IAM of 1.0 your not going to have much if any room for timing. Either way, you need to be watching for knock retard and knock correction when your tuning more so than IAM as often times the IAM wont drop until after a few knock events.
There are plenty of subaru tuning guides out there on the net, like this one:

I think you really want to get a firm grasp of how the knock control systems works before you start trying to fine-tune the base map.
