Lost ranked match. Does everyone lose same CSR?

Let’s say your team loses in Slayer or Team Arena. You are top of your team board. Will you lose the same amount of CSR as the person at the bottom of your team board?
Also if anyone knows, how much CSR do you lose for a loss? Thanks guys.
One more thing, why is it so much easier to rank up on a fresh account? I search balanced on Slayer ( was in a good team for over 20 matches ) and won 8/10 games went from Diamond 2 to eventually 4. On my smurf I won like 3 games and easily got to Diamond 5… My W/L is better on my main but I rank up so much slower…
If anyone is curious my smurf is: Slow noob shots

From what I can see its different for everyone. Say someone did horrible I think they loose more than someone who did great but still lost would.

How much each member of the team loses is solely dependent on their ranks relative to the opponents they faced.

Cool, thanks guys! I broke onyx on my smurf but even after winning a few games and losing one I go back to diamond 6. Frustrating…
