Well, far as i know there is no way to alter your score or stats other than doing it ingame by killing, dying ect.
Only way I an see to keep an acurate record like your wanting is to record them yourself. Since its just to see how your doing for yourself and setting goals or something then, thats probably the only way.
I seriously doubt HT is going to let ppl change things on the score page even if its to remove proxies or unearned kills. Just to much of a chance for it to be abused.
It would be nice if it listed real kills and proxie kills seperatly. unless it already does then sorry for not seeing it. I havent looked at the scores page in ages.
The way I determine how well im doing is how well I do on a given sortie especially if its against a stick I know.
Your post doesnt make you weird, its just we arent used to seeing this kind of post and it kinda confuses us. Im still expecting somebody to post how you stole their kill and they want the kill credited to their score or some such farfetched demand
