KPH is probably somewhere in the low 30s if you play mostly perfect. I only made 2 mistakes in this trip if I recall correctly and got 9 kills with one supply drop. Each supply drop should get you roughly one extra kill on the trip. The bonus for perfect kills does not apply to the supply drop. Teleport out if you don't have ~120 hp including food for next kill, chip damage here is massive.
