Probably the most useful thing for me would be if you try-hard when doing placements and up until you start gaining/losing ~ 24 SR per game. Maybe 30 games, including placements. Do it all in one season. Also write down the ranks (gold/plat/unranked/etc.) of each opponent and ally. Unfortunately, with private profiles, you can’t really track everyone’s SR reliably.
Essentially, you’d be adding more data to this: Initial Competitive Skill Rating, Decrypted and this Initial Competitive Skill Rating, Decrypted - Google Sheets. Though as I’ve said, you can’t track SR of other players anymore, so I wouldn’t bother with going through profiles like I did.
I don’t care how you level to 25, but let me know what you do.
LFG adds unknown factors (I’m currently either exploiting the LFG system, or finally getting the recognition I deserve, or LFG just uniquely suits my play style, or being lucky, not sure which), so please avoid that for the 30 games, and solo queue only.
Thanks.
