The role of lancers is to be exceptionally good at killing infantry with the drawback of being worse at everything else. They should be beaten by the worst Hussars, not trouncing the best Hussars in the game.
Your numbers seem right, but for reference, here’s the full comparison versus the best Hussar.
It was tested by multiple people in this thread and Chinacos win convincingly in groups.
Uhlans aren’t lancers. They don’t beat the best Hussar in the game AND have a x2.5 multiplier versus infantry. Lancers have a drawback to balance their anti-infantry strength, and that drawback is losing to generalist heavy cav. Chinacos have no business having a multiplier against them.
