    I'm sorry I didn't react the first time you reported a negative observation
    of 24680 96- 072 A. I sent a mail around Nov.30 to Tony that I expected a
    small orbit adjustment by 24680 in February, since it would be having
    passes too early (>239 minutes) before USA 116.
    
    I don't have any recent elsets for USA 116, but since my computation was
    based on drag terms .00021630  00000-0  28549-3, but where about 50 %
    higher early Jan., and seems to have been for a major part of the time
    between those elsets, the maneouvre would have to made earlier.
    
    I was expecting around -0.0015 on MM, so you might try
    USA 129         15.0  3.0  0.0  5.1 v
    1 24680U 96072  A 00009.55037090  .00030200  00000-0  43558-3 0  3988
    2 24680  97.9400  74.5371 0496601 138.9021 224.9456 14.78000000    05
    and expect about 0.5 min error margin per day of elset age.
    
    If USA 129 was boosted on Jan.10, USA 116 might pass about 210 minutes
    after USA 129 by now (decreasing)
    USA 116 guess
