Nick,

If you look at the 4th group of numbers in the first line (starts with
.1023) and compare it to the same group of numbers in a list of tle data
for several sats you will notice that even though .1023... is a small
number it is much larger than for the other sats. This value gets large as
the sat decays and the drag increases. Be very wary of tle data with a
large number in that position. Not a rigerous mathematical answer but handy
to know.
