... and my experience is that published elsets are bad in period and even more in drag, fluctuating much more than the physical reality. If you take observations ( I've done it with KHs and Lacrosses) or predictions near (a tracking station along the orbit at) the epoch, for several elsets to generate one new elset, it can be valid within about 1 km or less during the period (tried it with Starshine).
