Because if you're not WOT and want more power, put your foot down more. The argument could be made that obviously you could use it to maximise economy, but I think you'd want to tie that it with cam timing more than (but alongside) ignition timing. Again, you need a dyno for that.

The general method that I've learnt is generally
1. Cams
2. Fuel
3. Timing
Non-WOT is hard to dial in unless you have live tuning as you can't hold at a load region and adjust. So all you get is power runs. There is some theory that you want a smooth ignition map so perhaps you just total up the timing maps (beware of different axis settings), get your WOT timing sorted and then try and smooth in the timing from high load cruise (around 0.7/0.8 load) and WOT.
