Look let's do this realistically...
The scenario is entirely too set-piece and the intruder ships were hand picked to defeat the defender. The scenario depicted is the standard Trillion Credit tactic of overwhelming the defender with a mob of goblins. The thumb is distinctly on the scale.
To game this out properly, may I suggest the following changes to the scenario:
- Pull two opposing fleets from 'War Fleets of the 5FW'.
- Fight them by the doctrine and tactics described in 'The Fifth Frontier War', 'War Fleets' and 'Opening Moves'
- Resist mightily the urge to give each commander perfect intell and/or have the perfect solution for what the enemy does
- Remember that ships jumping into system DO NOT arrive together. Even with highly tuned drives and the best computers and software available operated by the most well trained and intuitive astrogators in each fleet, a full fleet WILL arrive over the course of hours on up to a full day. MWM displayed this in Agent of the Imperium so that's how we should wargame this out.
- Do not assume that every system operator is a skill level 4 master of their craft. Most systems on military vehicles are operated by 22 years old with, at most, skill level 2 in their assigned job task. They are supervised by skill level 3 and 4 experts but supervised is a long way from operated. Let's even be more realistic about it. The Zhodani ships have just completed a year-long very intensive training cycle, while Imperial vessels have been operating business as usual. So give the Zho crews skill level 2 and the Impies skill level 1.
From these start conditions game out the entire battle.
