Looking back at this topic, I'm fine whether Nappa's at 4,000 or 7,000.
Only thing that somewhat supports the notion of Nappa being close to Goku is this
Chapter: 226 (DBZ 32), P7.4, P8.1-4
Context: after Goku deflects Nappa's mouth blast
Vegeta: “Unbelievable!! To instantly deflect it at that short of a distance!”
Goku: “Phew. If I had taken that one head on, I’d have been in trouble!!”
Nappa: It…It can’t be!!! That was my…my best technique!!! He…He just bounced it off!!”
Goku: “He really is a tough bastard! Even though he should have been hit a little bit by my Kamehameha!! At this rate this looks like it will take forever...”
