Hmmm... I was assuming it was a dps because I was getting no-updates to auto-designs even after researching a higher level velocity-shard compared to shockwave torp.
In terms of research level:
Epsilon I, Epsilon II, Epsilon III, Velocity I, Velocity II, Velocity III
Epsilon I, Epsilon II, Epsilon III, Shockwave I, Shockwave II, Shockwave III
if I had Velocity I, the auto-designer chose Epsilon (or at least refused to auto-update the design to Velocity)
if I had Shockwave I and Velocity II, the auto-designer chose Shockwave I (or at least refused to auto-update the design to Velocity).
So, in the first, I have a higher-level plain & simple: Velocity I is a column 4 (level 4) tech, compared to a level 3 tech (column 3).
In the second, I have a column 5 tech vs. a column 4.
in both cases, the Velocity is on a lower-numbered row then either epsilon or shockwave... (but you're saying top right - which should favor Velicty, unless the real issue is position in research.txt or components.txt, or some UI sorting thing?)
