I’m not basing my understanding on my own experience, but the best documentation I have found. What I’m claiming is that new accounts and thrower accounts have an increased uncertainty about the skill of the player, and therefore increased willingness to adjust SR. Especially in a thrower account, I would expect the SR and MMR to have a large gap, with the MMR being higher than the SR, and therefore there are built in mechanisms to correct the SR toward the MMR.
