Looking at the screen with the cross-hairs it seems like the bottom right set of figures shows the distance to ISS, which was sitting at around 255m, and should go down to 235m (EDIT: was originally supposed to be 220m) before the crew on ISS tells dragon to head back to the 250m mark.

Here's hoping that they keep showing these shots from the ISS monitors throughout - kinda like watching someone coding but on a whole different level!
