Randomness of data disks

I think the fascination with purple disks is overrated.

I got one this time around and have yet to equip it. There are so many other combinations that do more.

Someone getting lots of blue disks while I’m getting all white would be a bigger concern for me. I think there could be a better progression of white to green to blue, but the purple disks are not all that important to me

Does anyone know whether by equipping 2 leader resolve cards you really get twice the bonuses e.g. +40% speed for the leader?
I have 2 identical leader resolve cards equipped, but given that my r3 Vader is often not going first (sector3) despite the fact that he should be at 350+ speed is a little confusing.
Thanks.

It's been said that all the cards are, in fact, cumulative.

That said, the "leader resolve" card was bugged during the initial normal mode rollout. In that case, the bug was that the Leader Resolve card was improving the stats of ALL allies, not just the leader. If Vader is going after other toons of yours, it's probably that they simply haven't fixed this yet and your other toons are also getting the bonus. If Vader is going after an enemy, I'm surprised, because I'm outracing the enemy easily with Vader, and it doesn't sound like your unmodified speed is less than mine.
