First Season performances

This is my first Season of playing LoL (LVL 30 since January)

Started from Bronze IV (placements), i'm currently PLAT V (but i manged to go through PLAT IV), just that i got demoted.

So, is there anyone who had a better performance than me ? ( ofc i expect there will be, but how far did you go ? ) Am i supposed to be glad i've reached so far ? Or i may have been lucky ?
