First of all, great work Skuzzy.
I assume the other two columns will also be linked to similar stats. I like the percentages and it might be nice to include them for the four columns on the main page. I also like seeing who you've killed (and who's killed you).
Here's a few other things I would like to see in similar format:
Ability to list by airframe (i.e. all 109's, all 190's, all Spits, etc. grouped)
Ability to list by category (i.e. fighter, fighter/attack, bomber, bomber/attack and GV)
Ability to list by date range (i.e. cumulative stats for tours 84 through 96 for example... although I'm sure you'll skip this one based on server load)
It would also be nice to be able to see total sorties by aircraft (or airframe or category). As it is, there's no accounting for sorties flown if there's no kills or deaths awarded.
Just a few ideas to add to your workload.
Regardless, I like the changes.
