I am confused. In the Tactics Trainer my rating is lower than the result on the chart. What is the difference between the rating on the left and the color chart on the right?

The Tactics Trainer rating graphs are slightly glitched, I think. My rating also shows as being higher on the graph than it actually is.

So one should go with the rating on the left, no?

Yes, the rating on the left is the accurate one. The graph should still display ups and downs correctly, but your rating will always seem a little boosted.

Wow and my bubble was looking so nice before it burst!
