Please explain the situation

Hello, folks!

My rating used to be 1450-1550. 

As you can see, It has been dropping all the way to 1200 in a recent weeks.

The reason is that I am constantly facing very strong players who play waaay above 1200-1300. I lost my last 3 games playing 80+ percent. My opponents simply played even better:

This one is my favorite:

First time in my life I played with 94% accuracy! Despite that I LOST to a 1230 player! Let me tell you, if I play with 'coach' on a 1200 level I will EASILY beat him like 10 times out of 10. 

Don't get me wrong, I am not complaining, I just to want to understand what is going on.

I think there is an explanation to it, please help friends.
