Charts? They're right here in the thread for anyone that cares to examine them.
Geometry? Try this. Draw a N/S line say 15 miles long. Put the target at the very S end. Put a dot 11 miles N and 2 E of the target dot.. that would be Milo, the attacker.
Assume the higher AFK target climbs N along the line at climb speed ~ 180 kts.
Know that the attacker has been radioed course and altitude on the target. Can he close the N/S line and climb up a few thousand feet to the target?
I think the math works. BTW, this is just a "math example" I don't have the EXACT locations. So relax and unclench your nose hair.
Which was it?
Both.

Sax and I were South, Milo and Rude almost or maybe even out of icon range to N.
Told them about the hi 51; told them there was no way Sax and I could get up that high. They leveled, got some speed, Milo did a climbing, turning intercept.
Hard to understand?
It wasn't a quick engagement.
IIRC, I looked up and saw the lead target LONG before I saw you trailing and had the target in ICON range long before I saw your icon.
I think you were just WAY out of position, too far in trail to do anything at all but dive on us once you got there.
...but like I said, remember it any way you like as it obviously upsets you to read it the way the four guys on the other side remember it.
Sleep well tonite!
