How does the research stats work?

So, I’ve just played a game with Delhi where I carried hard, had almost the better economy, killed the most enemies, and destroyed double building that my allies, but then I see I am in 9.4k points, other teammate 11k points, and other that I’ve just carried so hard (he got destroyed and I’ve helped him to recover) has 9.5k points.

I’d been looking in the stats to see why I am that low in score points, and I found I have 240 points on research, while everyone has more than 1k.

As delhi, I have almost every technology investigated and I passed to imperial age the first one, how does this points get assigned?

I can remember a few games where this happened too, and I’m pretty sure this happened using also Delhi, but I can’t confirm.
