Shredder for Android ELO ratings: Accurate?

It is a nonsense for me "I am able to be 1800 on chess.com in blitz so I should win 2700 from Chessmaster program easily in blitz". 

All games are recorded when we do rated games so yes I can show :  

And I didn't play especially tired or whatever excuse, just even at 1100 AI is not so weak as far as AI knows how to play fast and enough good, can be efficient in tactics.

In this game I was completely winning but you have to conclude in time otherwise it's lost on the clock.

Ok, so looking at that game i can see you confirmed what i thought: you were totally crushing Thorian (1100). It gave you away its queen, rook and everything, omg... 

If you lose one game on time, just play faster! as you can see Thorian will play bigger blunders than you without thinking.

At the moment I am 1438 after 32 games (22 wins, 2 draws, 8 losses).  I fall more on 1400's and my last game I also lost on the clock with winning position against AI. Ash (1400) but it's not "as overwhelming"

That's ok, just keep going. You will get a stable rating after a few hundred games. Then you can tell us your rating. I suppose it will be 2500 or more

And that's only for blitz time controls. You could do the same for classical and tell us.

Thank you

At the moment I am 1538 after 43 games (30 wins, 2 draws, 11 losses) and I just won my first 1600 

I believe that my level will be blocked between 1600 and 1800. I don't think it's possible that I can beat the +1800 because [of memory in time 20 minutes] the 1800's don't do "gifts" anymore and we have to more fight for winning or advantageous positions.

AI opponents even with losing positions manage to be dangerous and difficult to defeat. They are naturally strong in tactics, able to play very fast and quite well, know how to make pat combinations, know attack patterns that make them dangerous... in the end we have to have a lot of chess skills to be able to pass the 1800/2000 barrier in the long term. 

I watch also a chessmaster Personality Tournament time 5m+30 per moves where there is AI.Rick (2000) then all others from 2100 to AI.Chessmaster (without GM AIs) and the truth I observe is that the +2100 are in fact insane levels. For example AI.Dobie (2100) won AI.Jinx (2500) ( clearly even a human GMI could lose against AI.Dobie (2100) ) 

The levels from 2100 to 2600 seem to be somewhat the same and the levels form 2600 to 2900 seem to be somewhat the same.
