Would you like the option of having different material value numbers?

The standard "Reinfeld" 1-3-3-5-9 piece values are used on this site, but this article shows these numbers are not accurate and can lead to a variety of mistakes. https://www.chess.com/article/view/the-evaluation-of-material-imbalances-by-im-larry-kaufman

For example it is common for players to trade a knight and a bishop for a rook and a pawn because those 1-3-3-5-9 values imply it is an even trade when two minor pieces are usually worth more than a rook and a pawn.

Is there interest in giving users the option of changing from 1-3-3-5-9 numbers to an alternative piece valuation system, such as the Kaufman average piece values? 

Learning such things is part of advancing in chess.

But where would that be useful to chess.com users?

In the computer evaluations?

I assume that modern computer engines incorporate those nuances and that they update piece values based on the position.

These numbers appear beside the captured pieces during each game I play. It would be nice if I could change the material evaluation system so that it gives a decimal number here.

Nah, live chess is intended to mimic OTB chess, count the pieces and evaluate it yourself. 

Interesting topic, but as a progressing player, we all understand that the piece values change depending on the situation. However, the old values I feel are about as accurate as you can get regardless. 

Agreed. 

That's like saying the most accurate way to measure everybody's height is to the nearest foot.

Actually, it's not.

You just have to evaluate each position individually, the old method of piece counting is just a good guideline.

Here's a new video series by Larry Kaufman that explains the piece values: https://www.chess.com/lessons/advanced-piece-values/
