Minor Planet (52768) 1998 OR2 Close approach

Don't those elements change somewhat with every time step?

That's literally the Minor Planet Center's job. It is also a big expensive computation, especially if you do it for more than one minor planet. Why should everyone be sitting at their own devices waiting for individual calculations when the MPC could do it for everyone once? This is why we have ASTORB, but it isn't always reliable these days. Again, I believe that the MPC is letting the community down in this regard. They could at least adopt a shorter time period between their standard epochs.
