hmm, its not hard to evade an interdiction with such an nimble ship as the Asp...
can you please show one with you flying something more elegant, like an unengineered T9?
I thought more about this overnight and then I remembered what was bothering me about the claim that a T9 would be harder to do an evasion in.
From this >>> http://elite-dangerous.wikia.com/wiki/Frame_Shift_Drive_Interdictor <<< it is clear that the mass of the ships is also a factor as well as the speed of the ships.
The reason it is so easy for me in 4 of the 6 videos was because I deliberately slowed down to the minimum speed I can set in the ASPX before the interdiction began. The slower you are going when interdicted, the closer the interdicting ship must be and therefore the shorter the "thread" he has to jerk you around with.
Since the T9 is a lot slower than the ASP, it should make the thread even shorter so the interdicting ship has even less leverage to jerk you around. Add in the "MASS" factor and a small ship should find it next to impossible to interdict a T9 at minimum speed.
I have made a note to myself to test this.
You get a REP POINT for peaking my interest.
