Just lost a promotion series, and found myself down at 37 LP? Normally after a loss I am finding myself around 75... I do believe I encountered a bug here, 63 LP gone seems obscene from a series. Was gaining and losing around 14-17 LP a match.
Yea, a fluctuation of 15-22 points isn't that unheard of.
Most likely what happened, is that you won a few games in a streak which raised your MMR relative to the people you were facing. Due to that the system bumped up your LP gains/losses, as it was more unsure if your ranking was correct. Then you lost 3 in a row at a higher LP loss than you saw before your series. That sucks but not unfair or a bug.
You lose LP for every match you lost in promos, and you gain LP for the wins too. If you were in a Tier promo (you were) and lost 3 games (you did) you will lose 3 regular matches worth of LP. You did not win any back, or it would have been less.
How do Diamond players not know this?
