Sorry but looking at player vs player stats, you haven't killed me in the last 5 tours nor have I killed you. (that's as far back as I looked)
I did however kill Wingzero once tour 102 & once this current tour. Both times I was in a K4 and he was a Nik2.. No deaths of me by him or you are recorded in the stats.
You and I went 109k vs niki once that I saw. (tour 101)
You lost. (not that that says anything really as I don't remember the fight and can't say if it was a "legit" kill or not)
Wingzero is an excellent niki pilot. I ran into 'em three times last tour niki vs. niki. He tends to go for the forward shots a bit much for my taste, but all in all he knows how to fly that bird. He and I talked about it and he is of the opinion that the frontal shot in the N1K2 was "historically accurate" and is why he does them.
Personally, if the pilot isn't ho'n, I feel the spit's are a much easier ride over the niki. Spitfires out everyting the nik. The only advantage the niki has is ammo loadout (i.e. I will get more kills per hop in a niki vs. a spit) and it can drop flaps sooner. But I find it twice as easy to kill someone in a spit (8,9,16) over the niki.
