something very wrong with mmr

1)hey everyone.. so many people told me that this year's soft reset was crazy.. guys winning 6 out of their 10 placement games,or even 7 out 10 ended up 2 divsions down..( diamond to gold,plat to silver, gold to bronze) i am currently 1/3 and i was gold 3.. if my final winning streak is lets say 6/4 will i go in bronze mode? a guy that was master told me he got plat 4.. 2) if i stop playing dynamic q and wait for the new solo q,does this count as zero games in solo q or the games from dynamic q relate to solo q? thanks in advance*[slayer-jinx-catface]*
