To respond to Urchin's original idea, yes, I think something like that would work, but it would require some modifications.
1. The current scoring system allocates scoring points based on what kind of plane you killed. Additionally, the scoring system should subtract points based on the type of plane that killed you!
For example, if you are in a P51D and you let a Zeke sneak up on you, it should subtract a large number of points. If you are in a P51D and a 262 or Tempest comes roaring through and nails you, it should not cost too many points.
2. I don't know the point of HTC's pilot contest, but if many take it seriously, it will have an impact on high-risk encounters (furballs).
Therefore, I suggest HTC should further modify the scoring system so it takes distance from the nearest enemy base into account. If the nearest enemy base is close by, you don't get many points for the kill. NOTE: This does two things. 1) It doesn't give many points for vulch kills and 2) It would give a maximum number of points for base defense kills. (If you are defending your base, you are at a maximum distance from the nearest enemy field ... max points awarded.)
In the same vein as 2), I would suggest a third score modifier. Award more points for high altitude kills than low altitude kills.
Something like the following comes to mind:
N1 = enemy value of my plane
N2 = enemy value of my opponent's plane
Dist = distance to nearest enemy field
Alt = altitude of opponent when killed.
S1 = cumulative score from achieving kills
S2 = cumulative score from losing a fight
S1 = Sum [(N1/N2)*(Dist/15)*(alt/20000)]] over each fight you win.
S2 is calculated exactly as S1 is calculated, but it's the score from losing a fight. It's the cumulative S1 from those planes that killed you.
Fighter Rank = S1/(S2+1)
Notice the following:
a) furball kills occur near the deck. Therefore S1 would be decreased if you get too many furball kills. A decrease in S1 would lower your rank.
b) base capture kills occur near the deck and at a minimum distance from the nearest enemy field. if you spend too much time capturing bases, it's going to hurt your score.
c) base defense kills will help your score somewhat because they are at a maximum distance from the nearest enemy field --- but, they are low altitude kills.
d) The best kill would be base defense and kill of high altitude jabos or buffs.
e) If you get killed during base capture, it's really going to hurt, especially if a zeke or FM2 nails you.

You have committed the cardinal sins: Low altitude, close to an enemy base and killed by a high enemy value plane.
