Multiple bullets per gun

I've had a problem with the way we normalise our data - I think it should be normalised so that the area underneath the graph is 1, not the maximum value is 1. This would make this technique more useful, as you could simply integrate each gun over the hit area and use that as its hit ratio. I've also had the idea of dividing all my VG hit ratios by the random hit ratio - so that the gun hit-ratios are measured in a useful metric that adapts across bots. But back to designing my genetic gun-weight tuning algorithm!
