analyzing the games of the greats

does anyone know if there has been any analysis (using fritz or a comparable program) of the greats like capablanca, lasker etc etc to see if they actually played up to their reputations?

also speaking of fritz, im familiar with the backgammon programs like snowie and gnu and when they analyze a match it looks at your checker play and cube decisons and measures the equity lost for each and assigns a numeric value (error rate) and then a descriptive term (awful, beginner, novice, casual player, intermediate, advanced, expert, world class and supernatural). do the chess programs "grade" you similarly? ive never used fritz and was just curious.

This recent article on chessbase.com seems to be similar to what you're asking about:
