One thing I may add for every aspiring scoremonkey:
Doing things FOR score isn't wrong and can be fun too.
However, your road of enjoyment may lead downhill quite quickly if you start to stop doing certain things that you would enjoy otherwise, because they will "hurt" your score.
For example you would like to fly a Hurricane I or C.202, but you don't as they can fly only in fighter mode, which could be hurt by dying a lot in those "lousy" planes.
Or you feel like doing a few bomber sorties, but you can't because they reduce your damage hit%
This is the way to obsession and can quickly kill your enjoyment of Aces High.
And, unless you go for #1 rank, they aren't necessary, even if you still go for score. Only for the extreme top ranks such measures are necessary, staying in top 50 is very easily possible without limiting yourself too much. If you can't even make it to top 100, you "should" work on your general skills first.
I do one SdKfz sortie each tour, a few (2-5) strat runs in wirbel and B-25 per tour. That's about it what I do for score. What is helping in addition to that is that I rarely bomb GV'S (I kill em with guns) and I love to sink cruisers with my F6F. But I still occasionally deack or kill LVTs in fighter mode If I have to, without much adverse effect on my score.
I once tried to really play for score alone in LW arena - it was exhausting, boring and not much fun. And in the end my rank wasn't any better

And on fighter rank: In tour 113 I was flying mainly Tempest and 262 - ended up #2. In tour 112 I did fly 109G-2 (a 30 eny) plane, and still ended up #10.
In the end, no one cared about either result at all but me.

Always remember: The ones that you can impress by rank are surely not the ones you want to impress at all...
