Kinda relevant to the topic. I measured the acceleration of various aircraft in DCS at 40'000 ft from Mach 1 to Mach 1.5, clean, 60% fuel:

Code:
Viggen: 26 seconds
 M2000: 55 seconds
  F-15: 67 seconds
MiG-29: 72 seconds
Hornet: 93 secods
 Su-27: 96 seconds
MiG-21: 108 seconds
Low altitude performance seems believable, and Viggen is one of the slowest of the bunch at sea level, but at high altitude it's way off.

A little derail i know, but try dogfighting an AI viggen. most surprising. He will fly circles around any A/C.

Yes, high speed-high altitude performances are weird. HB should have a look at it

There's definitely something at odds!

There is data for 20k feet for the Viggen and a clean ac will accelerate from 1.0 to 1.5 in approximately 80sec.

The Viggen can go up to mach 1.34-1.35 when clean down on the deck in stage 3 burner. It wasnt really designed for high altitudes and going high mach's (at least the AJS variant).
