This does not appear to be correct based on statements published by CCP and my own experiments. CCP has previously stated that "Deceleration is simply acceleration in a direction opposed to the one you are travelling in, i.e. 'braking'." As a result, they only publish acceleration formulas because you're meant to invert them for deceleration at subwarp speeds. Acceleration and deceleration at warp speeds do seem to operate with different formulas for playability and performance reasons (having to do with how quickly people appear on grid) but that doesn't apply here since they're distinct from the subwarp formulas.
You can easily confirm this through testing - preferably with a larger ship since things happen a little slower. I used a Drake. In actuality, it takes a very long time to reach true top speed and true zero velocity (several minutes), so I simply used the rounded values registered on the display. From a dead stop to max velocity took exactly the same amount of time as max velocity to dead stop. I also checked the values between 10% to 90% of max velocity and 25% to 75% with the same result.
A ship accelerates to about 90% relatively quickly and likewise decelerates to about 10% relatively quickly. The last 10% on each end happens much slower because CCP uses a fluid dynamics model instead of a classical physics model. That's also what leads to your perception that acceleration is faster - you're rarely looking at your display waiting for that last little bit of max speed, but you do sometimes watch your gauges waiting for your speed to drop to zero. The reality is that they're happening at the same rate and they're both happening slowly.

I don't think this is true either. If you reverse direction, your ship doesn't spin on its axis and apply power - it turns in a smooth arc based on its agility and speed modifiers - and it does so under constant forward power. There might be some edge cases in which the act of turning a small agile ship under certain conditions cuts your speed at a greater rate than standard deceleration, but I haven't tested it. However, in the OP's case, such a maneuver would terminate the invulnerability timer, so that wouldn't work here regardless.
And to the OP's question then...yes - anything that impacts agility affects acceleration and deceleration equally since they use the same formulas. |
