But, should it be?

If you look at the figures awarded in the other route races, one earlier in the card and one immediately after the Derby, it is apparent the Derby used a different variant from those.

Race 4, raw figure 107, Beyer 93, variant 14
Race 10, raw figure 118, Beyer 109, variant 9
Race 11, raw figure 97, Beyer 83, variant 14

So, if he had used the same variant, the Beyer for the Derby would be 104. Given all the ground loss, it certainly seems reasonable. I wonder why he didn't.
