That's the important thing; Whether you had fun.
That said, I go check the web scores all the time, especially mine. I like to see how I'm doing and how I'm comparing to how I did last month. I even set goals of a sort for myself.
I know I'll never be in the top 100 in fighter scores, but I'll still have fun. Nonetheless, I set goals for myself, one being not to get killed in more than half the sorties I make. I can ditch, bail or get captured, but not killed. I go all out to avoid getting killed. So, for 100 sorties flown, the goal is to not get killed over 49 times. I'm usually successfull, but certainly getting killed is beyond your control many times. I usually make that goal, though.
I also try and improve my kill total, but that's more difficult to achieve. Last month I finally got over 200 fighter kills. I was kinda stoked by that but it really isn't that big a deal depending on how many sorties you made in the month. If you made umpteen thousand sorties and got two hundred kills, you need some work. A better goal would be to improve your kills per hour or the kill to sortie ratio.
Both those last ones would be harder to judge improvement on, though, because sometimes I have a hard time finding a fight, much less a good one. So, if I spend three flights flying around trying to find a fight and come up empty handed, I can hardly blame myself for having a poor kill per sortie ratio, at least for those type of flights.
I'll also often check the scores of guys (and gals) that shoot me down. It's interesting, when someone just handed you your head on a platter, to find out his scores are much lower than yours, and someone you just creamed is one of the better flyers.
Also interesting is seeing flyers with high hit percentages but low kill per hour ratios and vice versa. Weird how the scores vary so much.
The scoreboard is quite interesting to those of us without lives.
