Switch evaluation from stockfish to tablebase

[emilioferrucci]

I was looking at the candidates games today, and there were a few times in the Fabi-MVL endgame where the tablebase evaluation went from drawn to winning for Fabi and back (moves 55, 60, 62), yet the server's stockfish evaluation remained almost constant.

Why not make the computer analysis graph display the tablebase evaluation instead of stockfish's when there are 7 pieces or fewer (and the position is not "unknown")?

Yes I agree that in tablebases positions the evaluation should change, since fishnet doesn't seem to use tablebases
Maybe the graph color could change to indicate this change to absolute truth

Also, tablebases are very helpful for very long DTMs
