Hi, I lost a ridiculous amount of Elo, is this a bug?

The game in question was this one:

For example, the other player on 8th place who tied with me had more Elo than me (210), even had higher win chances against the other players against whom they lost, yet they dropped 35 Elo, I on the other hand had 202 Elo and dropped by 102 (probably would have been more, if 100 wasn't the cap).

How was this Elo even calculated? I guess I should never play real time games?

In you first 11 games you gain\lose triple amount on elo and double in next 10 games after that. You droppen around 35*3=105 but lost only 102 because you can't go under 100
