Burn Retros isn't dependent on the number of successes rolled, it's just a Pilot+Maneuver check at +0, or automatic at higher speeds. Maybe I'm misunderstanding something, but here's the quoted passage from TGT's Rules thread:<br/><br/><div class="quoteheader"><div class="topslice_quote">Quote</div></div><blockquote class="bbc_standard_quote">Burn Retros: In place of a ship's normal maneuver, the commander of the ship may simply fire the retro rockets of the ship, causing its speed to be reduced.  If the ship is moving faster than its cruising speed, its speed is reduced to its cruising speed.  If the ship is moving at cruising speed or slower, its speed is reduced to its combat speed.  If a ship burns retros at combat speed or slower, the helmsman must make a  challenging (+0) Pilot + Maneuverability test.  On a success, the ship comes to a stop.  On a failure, the ship's speed is only reduced by 1 VU.  A ship may combine burning retros with any other maneuver with no increase in difficulty.<br/></blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>You were moving at Cruising Speed of 13. That automatically reduces you to Combat speed of 7, no check necessary. He did likewise, moving from his previous speed of 21 to his Cruising speed of 10. He did actually slow down faster than you here, because the difference between his current and Cruise speeds was larger than your Cruise speed and Combat speed.<br/><br/>I suppose you could instead apply that otherwise wasted Piloting roll on an Adjust Speed order, letting you drop your speed to anywhere between 6 and 0 with those successes, but you would have done so before he also reduced speeds, and you weren't aware of his own cruising speed till now.<br/><br/>
