Oooh i made a small editor for this... some 10 years ago! It's still on my site at the Archive:

Place it on the Gamedat directory and run wca-g.exe. This was a really simple program, actually. It read the gauntlet file, displayed the configuration for each wave and allowed you to change each one of them, so you could build your own gauntlet if you wanted to. You could specify ship type, number of ships and pilot skill level (1-4) for each wave.
The Academy gauntlet is configured to throw at you the following waves:
Level 01, Wave 1 - 1 Sartha, skill 1
Level 01, Wave 2 - 1 Drakhri, skill 1
Level 01, Wave 3 - 1 Jrathek, skill 1
Level 02, Wave 1 - 2 Sartha, skill 1
Level 02, Wave 2 - 2 Drakhri, skill 1
Level 02, Wave 3 - 2 Jalkehi, skill 1
Level 03, Wave 1 - 2 Grikath, skill 1
Level 03, Wave 2 - 2 Strakha, skill 1
Level 03, Wave 3 - 3 Ferret, skill 1
Level 04, Wave 1 - 1 Wraith, skill 1
Level 04, Wave 2 - 2 Epee, skill 1
Level 04, Wave 3 - 3 Sabre, skill 1
Level 05, Wave 1 - 3 Epee, skill 1
Level 05, Wave 2 - 1 Sabre, skill 1
Level 05, Wave 3 - 3 Broadsword, skill 1
Level 06, Wave 1 - 1 Dorkathi, skill 1

Level 14, Wave 3 - 10 Sartha, skill 4
Level 15, Wave 1 - 7 Morningstar, skill 4
Level 15, Wave 2 - 8 Wraith, skill 3
Level 15, Wave 3 - 8 Jrathek, skill 4
However, i seem to recall that, as you started to hit memory limits, Academy stopped adding ships to the action sphere. For this reason, you may not actually face 10 Sartha on Level 14/3, for example, but slightly less than that.
And by the way, I don't think i ever got past Level 11 either...
